Further, a foresail is coupled to the luff cable such that at least a portion of the foresail is movable relative to the longitudinal axis upon movement of the luff cable.
Description




BACKGROUND OF THE INVENTION




The invention relates generally to the field of sailing. More specifically, the invention relates to the operation and management of sails on sailboats.




Sailing has long been a popular sport. One particular type of sailboat which is of interest to the present invention is illustrated generally in FIG.


1


. It is identified by referenced numeral


10


. Sailboat


10


comprises a hull (not shown) and a deck


12


disposed on top of the hull. At a back end of boat


10


is the stern


14


, while at the front end is the fore peak


16


. Extending between fore peak


16


and stern


14


(i.e., along a center of deck


12


) is a central axis


18


. Central axis


18


divides sailboat


10


into port side


20


and a starboard side


22


. At the front end of sailboat


10


is the bow


24


.




Extending generally vertically upward from deck


12


is a mast


26


. Mast


26


is aligned with central axis


18


and is held in place by a forestay or headstay


28


, a backstay


30


, and pair of shrouds


32


and


34


. However, it will be appreciated that multiple stays and shrouds may be employed in various arrangements and combinations. Forestay


28


is attached to deck


12


at a stemhead fitting


36


which lies on central axis


18


. Since the opposite end of forestay


28


is attached to mast


26


, forestay


28


is generally parallel with central axis


18


. Backstay


30


is attached to deck


12


by a backstay fitting


38


. At its opposite end, backstay


30


is attached to mast


26


at a masthead


40


.




The current method for rigging a foresail, such as a jib, on sailboat


10


is by use of forestay


28


. The foresail is raised along forestay


28


which in turn serves as the axis point for rotating the foresail. However, because forestay


28


has the additional function of securing mast


26


, forestay


28


cannot be moved from its securing points on mast


26


and deck


12


. Although a variety of methods may be employed to attach the foresail to headstay


28


, headstay


28


remains the axis point of the foresail. Since headstay


28


is the attachment point of the foresail, the axis of rotation of the foresail is always fixed at central axis


18


. Such a configuration can limit the usefulness of the foresail and its cooperation with the main sail. For example, in some cases the main sail may block a significant amount of wind from the foresail to limit the speed of the sail boat.




Another drawback to sailboat


10


is the difficulty encountered by a sailor when changing the foresail. Changing of the foresail with current rigging equipment requires one or more of the crew members to exit a cabin


42


and proceed onto bow


24


so that the foresail can be removed from forestay


28


and replaced with another sail. However, the addition of one or more crew members on the bow


24


will cause a change in the attitude of the boat in the water, thereby slowing the speed of the boat. Another disadvantage is that it may become dangerous for crew members to be positioned on bow


24


, particularly when another sail also occupies bow


24


. A further disadvantage is that it is time consuming to have a crew member exit cabin


42


and proceed to forestay


28


to change the sail. One significant disadvantage in changing foresails is that the speed of the boat is reduced because of the time in which no foresail is in place.




Hence, it would be desirable to provide improved sailboats which will greatly reduce or eliminate the problems associated with prior art sailboats. For example, in one embodiment, it would be desirable to provide a sailboat having a more versatile foresail arrangement and where the use of the foresail and its cooperation with the main sail were optimized. It would further be desirable to provide a more efficient way to manage the foresail, including providing an easy and convenient way to raise and lower the foresail.




SUMMARY OF THE INVENTION




The invention provides improved sailboats and methods for their construction and use. One important feature of at least some embodiments of the invention is that the foresail is provided with an axis of rotation (typically at the luff of the foresail) that can be located essentially anywhere on the bow of the boat. The axis of rotation of the foresail will preferably be variable so that its location may be varied both toward and away from a central axis of the boat as well as in the fore and aft directions. In this way, both the head and the tack of the foresail may be moved away from the longitudinal axis on both sides of the boat, regardless of the direction of the wind. As such, both the head and the tack may be moved to a windward side of the sailboat such that wind may engage the foresail and not be substantially blocked by the mainsail when traveling downwind. Preferably, such features will be provided by coupling the foresail to a wire, cable, line or the like which is separate from the forestay or headstay. In this way, the axis of rotation of the foresail may be located away from the central axis of the boat. Further, various tracks may be provided on the boat or the mast to allow for the location of the cable to which the foresail is attached to be varied.




In one exemplary embodiment, the invention provides a sailboat which comprises a hull and a deck which is operably attached to the hull. The deck includes a longitudinal axis which extends along a center of the deck. A mast is further provided and is generally aligned with the longitudinal axis. A luff cable is coupled to the mast and the deck, with the luff cable being movable relative to the longitudinal axis. Further, a foresail is coupled to the luff cable such that at least a portion of the foresail is movable relative to the longitudinal axis upon movement of the luff cable.




The luff cable is preferably coupled to the mast and the deck such that the luff cable can be moved toward and away from the central axis, in the fore and aft directions, or both. In this way, the location of the rotational axis of the foresail may be positioned essentially anywhere fore of the mast. With such a configuration, the speed of the sailboat may be increased regardless of the direction of the boat in relation to the wind. More importantly, such a configuration improves the direction of the sailboat relative to the direction of the wind.




Typically, the foresail includes a head, a tack, and a clue, with the foresail being coupled to a luff cable between the head and the tack. Preferably, the luff cable is movably coupled to the deck to allow the tack to be movable relative to the longitudinal axis. In another aspect, the luff cable may be movably coupled to the mast to allow the head of the foresail to be movable relative to the longitudinal axis.




In one particularly preferable aspect, a track is operably attached to the deck, with at least a portion of the track being at an angle relative to the longitudinal axis. The luff cable is coupled to the track so that the location of the luff cable along the bow of the deck may be varied. The track may be disposed at various locations along the deck and may have various configurations, including straight tracks, angled tracks, curved tracks and the like. For example, the track may be conveniently disposed about a periphery of the deck. Typically, a carriage will be coupled to the track, with the luff cable being coupled to the carriage. The carriage may be moved by one or more lines or cables that are coupled to the carriage. Alternatively, the carriage may move along the track depending on the direction of the wind to allow the foresail to automatically adjust its position depending on the wind direction.




In one alternative aspect, a turret is rotatably coupled to the deck, and an arm is translatably coupled to the turret. The luff cable is coupled to the arm to allow the tack of the foresail to be moved both rotationally and radially relative to the turret. Use of such a turret is particularly advantageous in that it may be employed to move the tack of the foresail to an angle of up to approximately 45 to 50 degrees relative to the mast and the longitudinal axis to allow the boat to sail into the wind. Further, the tack of the foresail may be retracted when moving the tack to the other side of the boat so that the tack will not interfere with the forestay.




In still another alternative, a sprit pole is coupled to both the port side and the starboard side of the sailboat. A line extends between the sprit poles, and the tack is movably coupled to the line. In this way, the position of the tack may be varied by moving the tack along the line. Conveniently, positioning of the tack along the line may be accomplished by allowing the tack to move along the line depending on the direction of the wind. Preferably, the sprit poles are translatable relative to the hull to increase the distance that the tack is positioned away from the mast.




In still a further aspect, a plurality of attachment points may be provided on the deck which are offset from the longitudinal axis. In this way, the luff cable may be manually attached to the attachment points to vary the location of the tack relative to the longitudinal axis.




The sailboat preferably also includes a mainsail that is coupled to the mast. A boom is also coupled to the mainsail to move the mainsail as is known in the art. Further, a boom pole is coupled to the boom to adjust the orientation of the mainsail. Use of the boom pole is particularly advantageous in that it allows the mainsail to be positioned at an orientation having the same general relationship between the mainsail and the foresail as presently exists with conventional sailboats so that full advantage can be taken of this relationship.




In another exemplary aspect, a track is also operably attached to the mast to raise and lower the luff cable relative to the mast. An adjustment mechanism is preferably coupled to the mast track to vary the location of the luff cable relative to the longitudinal axis. For example, the adjustment mechanism may comprise a cross member having a track to which the luff cable is coupled. The cross member is movably coupled to the mast track so that the cross member may be raised and lowered. To move the luff cable toward or away from the central axis, the luff cable is simply moved along the track of the cross member. Alternatively, the adjustment mechanism may comprise a pivotable strut which is coupled to the mast track. In this way, the luff cable may be moved in a variety of directions relative to the mast.




In one aspect, a cable of fixed length is coupled to the mast track at a location that is different from the strut. The other end of the cable is attached to the foresail. In this way, as the strut is moved along the track relative to the cable, the position of the head of the foresail relative to the mast is adjusted. Such a configuration is particularly advantageous in that the strut may be moved inside the forestay so that the head of the foresail may be moved to the opposite side of the sailboat without interfering with the forestay. Once the foresail is moved to the opposite side of the boat, the strut is moved further along the track to move the head of the foresail away from the mast. The head of the foresail may also be moved by coupling a line or cable to the shroud and the strut. The line may then be manipulated to adjust the position of the head of the foresail relative to the mast helping tension the luff cable of the foresail.




The foresail is preferably raised by moving the luff cable along the deck in a direction generally toward the fore peak while also moving the luff cable up the mast until tension is provided to the luff cable. Once the sail is raised, the location of the luff cable may be varied along the bow of the deck to vary the location of the tack. Optionally, the location of the luff cable may also be varied relative to the mast to vary the location of the head of the foresail. As with conventional sailboats, the location of the clew may also be varied as is known in the art. In this way, an almost infinite variety of sail locations may be provided to optimize the cooperation of the foresail with the main sail. Advantageously, the deck track and the mast track may terminate in the vicinity of the cockpit or cabin so that the foresail may be raised or lowered while the crew remain within or near the cabin area. In this way, excessive weight is not transferred to the bow of the boat. Further, the need for placing crew members on the bow of the deck is eliminated.




In another exemplary embodiment, the invention provides a sailboat which comprises a hull and a deck that is operably attached to the hull. The deck has a longitudinal axis that extends along the center of the deck. A mast is generally aligned with the longitudinal axis. Further, at least two tracks are disposed on the deck and on the mast. In this way, each of the tracks may be used to raise or lower a different foresail. In this manner, operation of the sailboat may be optimized since one sail may remain raised while raising another sail. Once the second sail is raised, the first sail may be lowered and removed. As an alternative to using tracks, a pair of pulleys may be coupled to the mask and the deck to allow two foresails to be separately raised and lowered.




Preferably, a luff cable is attached to each of the tracks and is coupled to one of the foresails. In this way, each foresail may be raised by moving the luff cable along one of the deck tracks and up one of the mast tracks. In another aspect, the deck tracks are disposed on opposite sides of the longitudinal axis. In some cases, the tracks on the deck and the mast intersect each other at a point aligned with the longitudinal axis so that the head and the tack of the foresail remain on the longitudinal axis when fully raised. In a further aspect, at least a portion of the deck tracks are disposed at an angle relative to the longitudinal axis. In this way, the foresail may be moved both toward and away from the longitudinal axis so that the rotational axis of the foresail may be varied. In still another aspect, an adjustable strut or cross member may be coupled to at least one of the mast tracks so that the luff cable may be moved either toward or away from the mast when coupled to the adjustable strut or cross member. Conveniently, the mast track or tracks and the deck track or tracks may begin near the cockpit so that the various foresails may be raised and lowered while the crew remain in or near the cabin area.




In another embodiment, the invention provides a sailboat comprising a hull and a deck operably attached to the hull, with the deck having a longitudinal axis extending along a center of the deck. A mast extends from the deck and is generally aligned with the longitudinal axis. A boom is pivotally coupled to the mast. The sailboat further includes a foresail having a head, a tack and a clew. The head of the foresail is operably coupled to the mast using one of the methods described herein and the tack is operably coupled to the boom. In this way, the tack is movable in an operating direction that is different from a longitudinal direction defined by the longitudinal axis by pivoting the boom about the mast.




Optionally, the boom includes an extension, and the tack is coupled to the extension. In this way, the tack may be moved toward or away from the mast by translating the extension. Preferably, the sailboat further includes a track that is coupled to the deck, a carriage that is coupled to the track, and a boom pole that is pivotally coupled to the boom and the carriage. A mechanism is also provided for moving the carriage along the track. In this way, the orientation of the foresail may be varied simply by moving the position of the carriage along the track.




The invention further provides an exemplary method for retrofitting a sailboat to accommodate a foresail having a variable foresail axis. According to the method, a track is coupled to a deck of the sailboat as well as to a mast of the sailboat. In this way, the foresail may be raised and lowered by coupling the foresail to a luff cable and moving the luff cable along the deck track and the mast track. Preferably, at least a portion of the deck track is at an angle relative to a longitudinal axis of the boat so that the foresail may be movable relative to the longitudinal axis. Optionally, two or more deck tracks may be coupled to both the deck and the mast to allow separate foresails to be separately raised and lowered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The invention provides exemplary sailboats and methods for their construction and use. The features of the invention will find their greatest use with sailboats having one hull. However, it will be appreciated that the invention may also be useful with sailboats having multiple hulls, e.g. catamaran sailboats. One important feature of the invention is that it provides a way to vary the location of the rotational axis of the foresail (which is typically at the luff of the foresail) relative to the sailboat. In this way, the use of the foresail and its cooperation with the main sail may be optimized so that boat speed may be increased regardless of wind direction. The location of the rotational axis of the foresail is preferably varied by moving the location of the tack and/or head of the foresail. In certain preferred embodiments, the location of the rotational axis of the foresail is made variable by attaching the foresail to a luff cable, wire, line and the like and varying the attachment points of the luff cable on the deck and/or the mast. In this way, the rotation of the axis of the foresail may be placed in an almost infinite variety of orientations simply by moving the luff cable to different locations relative to the deck and/or relative to the mast. More specifically, the attachment points of the luff cable to the mast and the deck may be moved either fore, aft, toward, or away from the central axis of the sailboat to vary the orientation and location of the rotational axis of the foresail.




Another important feature of the invention is that it provides a convenient way to raise a foresail. This is preferably accomplished by providing a track along the deck and a track along the mast, with the two tracks terminating near the cockpit or cabin of the sailboat. In this way, the luff cable (having the foresail attached) can be moved along the deck toward the fore peak and up the mast to provide tension to the luff cable and raise the foresail. In this manner, a sailor need not exit the cabin or cockpit to raise or lower the foresail. Further, such a configuration allows the foresail to be raised and lowered more efficiently and more safely and can provide significant advantages when racing the sailboat.




Still another important feature of the invention is that the sailboats may be provided with two or more sets of tracks on the deck and the mast. In this way, two or more sails may be separately operated. For example, one foresail may remain raised while preparing to raise another foresail. Once the other foresail is raised, the first foresail may be lowered. In this manner, the sailboat will essentially always have a foresail available for operation.




Referring now to

FIG. 2

, an exemplary embodiment of a sailboat


44


will be described. Sailboat


44


is constructed of various elements that are essentially identical to sailboat


10


of FIG.


1


. For convenience of discussion, identical elements of all embodiments described herein will be described using the same reference numerals as used to describe sailboat


10


.




Attached to deck


12


near forepeak


16


is a support


46


having a track


48


. Track


48


as well as the other tracks described herein may be any one of a variety of commercially available tracks, such as those commercially available from Harken, Inc. Track


48


is generally perpendicular to central axis


18


, although track


48


could be arranged at other angles relative to central axis


18


and can also be provided with other geometries, such as curved, angled, elliptical, and the like. Coupled to track


48


is a carriage


50


which is movable along track


48


. Coupled to carriage


50


is a luff cable


52


. Although not shown, luff cable


52


will typically have a foresail operably attached thereto. In this way, luff cable


52


serves as the rotational axis for the foresail. As carriage


50


is moved along track


48


, luff cable


52


is also moved to move the location of the rotational axis of the foresail. Conveniently, support


46


is secured to sailboat


44


by guy wires


54


which in turn are coupled to a pair of chain plates


56


(shown in phantom line) on the hull of the sailboat.




Carriage


50


is moved along track


48


by operating a control cable


58


. Control cable


58


extends from cabin


42


, around a cleat


60


, adjacent a sheave


62


on deck


12


, around another sheave


64


on support


46


, and then to carriage


50


. From carriage


50


, control cable


58


extends around another sheave


66


, to a sheave


68


, around a cleat


70


, and back into cabin


42


. In this manner, carriage


50


may be moved along track


48


simply by releasing control cable


58


from cleats


60


and


70


and pulling on either end of control cable


58


.




As best shown in

FIGS. 2 and 3

, mast


26


includes a track


72


which allows luff cable


52


to be raised and lowered as described hereinafter. Coupled to track


72


by an elongate carriage


78


is a cross-member


74


. A track


76


is disposed on cross-member


74


. Carriage


78


is movable along track


72


so that it may move cross-member


74


up and down mast


26


. An eyelet


80


is provided at masthead


40


. A pulley (not shown) is coupled to eyelet


80


SO that a cable (not shown) may be disposed within track


76


(or within mast


26


or along side of mast


26


) and extend around the pulley to allow the cable to be used to lift carriage


78


, and thus move cross-member


74


. To lower cross-member


74


, the cable (not shown) is simply released, allowing carriage


78


(and thus cross-member


74


) to move down track


72


by force of gravity. In some cases, carriage


78


may be lowered by pulling on the foresail or by using a cable that is coupled to carriage


78


. Conveniently, a set of guy wires


82


-


88


are provided to secure cross-member


74


to carriage


78


. In this way, cross-member


74


is stabilized relative to mast


26


.




Coupled to track


76


of cross-member


74


is a carriage


90


. Attached to carriage


90


is luff cable


52


. As carriage


90


is moved along track


76


, the horizontal location of luff cable


52


is varied. As previously described, the other end of luff cable


52


is coupled to carriage


50


on support


46


(see FIG.


2


). In this way, the position of luff cable


52


relative to the sailboat may be varied either by moving carriage


50


or carriage


90


, or both, so that a wide variety of orientations for luff cable


52


may be obtained. In this manner, the rotational axis of the foresail can be moved to a variety of locations in an easy and convenient manner.




Still referring to

FIGS. 2 and 3

, carriage


90


is moved along track


76


by use of a control cable


92


. Control cable


92


initiates within cabin


42


and extends around a pair sheaves


94


and


96


where it is directed upward on mast


26


. Control cable


92


is coupled to mast


26


by a sheave


98


. From sheave


98


, control cable


92


extends to a sheave


100


on cross-member


74


. Control cable


92


is then coupled to carriage


90


and then extends to a sheave


102


at an opposite end of cross-member


74


. Finally, control cable


92


passes around sheaves


104


-


108


until terminating within cabin


42


. In this manner, a sailor within cabin


42


may move carriage


90


along track


76


by simply pulling on either end of control cable


92


while remaining within cabin


42


.




Referring now to

FIGS. 4 and 5

, an exemplary method for raising a foresail


110


on sailboat


44


will be described. Foresail


110


includes a tack


112


, a head


114


, and a clew


116


. Luff cable


52


is attached to foresail


110


between tack


112


and head


114


as shown. Luff cable


52


is initially threaded through carriage


50


and brought back within cabin


42


. The other end of luff cable


52


is coupled to carriage


90


. Preferably, cross-member


74


is lowered along track


72


so that luff cable


52


may be coupled to carriage


90


from within cabin


42


. Luff cable


52


is then pulled from within cabin


42


to move tack


112


toward carriage


50


. Cross-member


74


is also raised along track


72


to move head


114


upwardly along mast


26


. This process is continued until luff cable


52


has the desired tension as illustrated in FIG.


5


. At any time, carriage


50


and/or carriage


90


may be moved to change the orientation of luff cable


52


and foresail


110


. As previously described, the orientation of luff cable


52


may be varied within the cabin by manipulating control cable


58


and/or control cable


92


.




Referring to

FIG. 6

, an alternative embodiment of a sailboat


118


will be described. Sailboat


118


includes a track


120


which extends about the periphery of bow


24


. Coupled to track


120


is a carriage


122


to which a luff cable may be attached to vary the rotational axis of a foresail similar to that previously described with sailboat


44


.




Carriage


122


is moved along track


120


by use of a control cable


124


. Control cable


124


extends from cabin


42


, along a cleat


126


, along a sheave


128


, and to carriage


122


. From carriage


122


, control cable


124


runs back along a sheave


130


and a cleat


132


where it terminates within cabin


42


. In this way, a sailor may move carriage


122


along track


120


by pulling on control cable


124


while remaining within cabin


42


.




Mast


26


includes a track


134


which is used to raise and lower the other end of the luff cable similar to sailboat


44


. Instead of employing a cross-member to raise the luff cable on mast


26


, a simple carriage may be coupled to track


134


to raise or lower the luff cable (not shown). As another alternative, an adjustable strut


136


(see

FIGS. 7 and 12

) may be employed to allow the location of the luff cable to be varied relative to the mast. Adjustable strut


136


will be described in greater detail with reference to FIG.


12


.




Referring now to

FIGS. 7 and 8

, an exemplary method for raising a foresail


138


on sailboat


118


will be described. Foresail


138


includes a tack


140


, a head


142


, and a clew


144


. Foresail


138


is attached to a luff cable


146


between head


142


and tack


140


. Luff cable


146


is attached to carriage


122


, preferably while carriage


122


is dislocated near sheave


128


or sheave


130


. In this way, a sailor need not exit cabin


42


in order to attach luff cable


146


to carriage


122


. The other end of luff cable


146


(i.e., near head


142


) is attached to a carriage


148


which is coupled to track


134


. Luff cable


146


is preferably attached to carriage


148


while carriage


148


is lowered so that coupling or attachment may occur from within cabin


42


. Control cable


124


is then pulled from within cabin


42


to move carriage


122


toward forepeak


16


shown in FIG.


8


. Carriage


122


may be stopped anywhere along track


120


depending on where it is desired to locate foresail


138


. Carriage


148


is also raised up track


134


until proper tension is provided in luff cable


146


. Carriage


148


is raised using a cable (not shown) which runs the length of mast


26


. As described in greater detail with reference to

FIG. 12

, adjustable strut


136


allows for the location of head


142


to be varied relative to mast


26


. In this way, luff cable


146


may be placed in a wide variety of orientations so that the rotational axis of foresail


138


may be greatly varied. Further, a line


150


is attached to clew


144


as is known in the art to vary the location of clew


144


.




Referring now to

FIG. 9

, still another embodiment of a sailboat


152


will be described. Sailboat


152


includes a port track


154


and a starboard track


156


. Coupled to port track


154


is a carriage


158


, and coupled to starboard track


156


is a carriage


160


. In this manner, a luff cable


182


may be attached either to carriage


158


or carriage


160


, or both. With this arrangement, the rotational axis of the foresail may be varied on the port side using carriage


158


or on the starboard side using carriage


160


. Further, use of two separate tracks with two separate luff cables allows for two foresails to be separately raised and lowered in a manner similar to that described hereinafter with reference to FIG.


11


.




Carriage


158


is moved along track


154


using a control cable


164


. Cable


164


is routed around a pair of turning blocks


166


and


168


and around a sheave


170


. Similarly, carriage


160


is moved by a control cable


172


which is routed around a pair of turning blocks


174


,


176


and a sheave


178


. In this way, either control cable


164


or control cable


172


may be operated from within cabin


42


to move the rotational axis of the foresail. Mast


26


includes a track


180


for raising or lowering luff cable


182


in a manner similar to that described with previous embodiments.




Referring to

FIG. 10

, still another embodiment of a sailboat


184


will be described. Sailboat


184


includes a track


186


that extends beyond the deck


12


. Track


186


is supported by a pair of supports


188


. Coupled to track


186


is a carriage


190


which in turn is coupled to a luff cable


192


. As with other embodiments, carriage


190


may be moved about track


186


to vary the rotational axis of the foresail. Carriage


190


is moved along track


186


by operating a control cable


194


. Control cable


194


begins in cabin


42


and extends along a cleat


196


and a sheave


198


before reaching carriage


190


. Control cable


194


then extends past a sheave


200


, along a cleat


202


and back into cabin


42


. In this way, carriage


190


may be moved from within cabin


42


. Mast


26


includes a track


204


for raising or lowering the other end of luff cable


192


in a manner similar to other embodiments to raise or lower the foresail.




Referring to

FIG. 11

, still yet another embodiment of a sailboat


206


will be described. Sailboat


206


includes a pair of deck tracks


208


,


210


and a pair of mast tracks


212


,


214


. Coupled to each of tracks


208


-


214


is a carriage


216


-


222


, respectively (with carriage


222


being illustrated in FIG.


12


). Carriage


216


operates in cooperation with carriage


220


to raise a foresail that is attached to a luff cable (not shown). Similarly, carriage


218


works in combination with carriage


222


to raise and lower a foresail using a luff cable


224


. In this way, two sails may be separately raised and lowered while remaining within cabin


42


. Such a system is particularly advantageous when changing sails since one sail may remain raised while the other is loaded onto the carriages. Once the second sail is raised, the first sail may be lowered so that at least one foresail is operating at all times. Further, although not shown, the orientation of the deck tracks may be varied along deck


12


so that the rotational axis of the foresail may be varied as described in previous embodiments.




Carriage


216


is moved along track


208


by a control cable


226


while carriage


218


is moved along track


210


by a control cable


228


. Carriages


220


and


222


are raised and lowered using control cables (not shown) which may be positioned about sheaves disposed on mast


26


.




Referring now to

FIG. 12

, an adjustment mechanism


230


for adjusting the location of luff cable


224


will be described. Adjustment mechanism


230


comprises adjustable strut


136


having a loop


234


(or other attachment mechanism) which is coupled to a carriage


232


on track


214


. In this way, strut


136


may be pivoted about a wide variety of angles relative to mast


26


. Adjustable strut


136


comprises a tubular body


236


and a shaft


238


. Shaft


238


is provided with a plurality of holes


240


into which a pin and clip


242


may be placed to vary the length of strut


136


. With such a configuration, a way is provided to vary the offset of luff cable


224


relative to the centerline of the boat. Connected to shaft


238


is a pulley


244


upon which luff cable


224


is guided.




Carriage


222


is connected to carriage


232


by a control cable


246


. Control cable


246


passes around a pulley


248


so that the distance between carriages


222


and


232


may be varied by pulling on control cable


246


while remaining within cabin


42


. Although not shown, other control cables may be provided to control movement of strut


136


to control lateral movement, i.e., toward and away from central axis


18


.




Although not shown, an adjustable strut similar to strut


136


may be provided on track


212


. Alternatively, tracks


212


and


214


may be provided with a cross-member similar to the cross-member of

FIG. 3

to vary the location of luff cable


224


.




As illustrated in

FIG. 13

, adjustable strut


136


may also be used with sailboat


118


of FIG.


6


. To accommodate strut


136


, a carriage


300


is coupled to track


120


and strut


136


is pivotally coupled to carriage


300


. A control cable


302


which begins in cabin


42


extends past a cleat


304


, around a pulley


306


and to carriage


300


. In this way, a crew member may tighten or loosen cable


302


to vary the location of carriage


300


relative to carriage


122


. In so doing, the crew member is able to adjust both the tension in and the orientation of a luff cable


308


. Although not shown, carriage


300


(or another carriage) may be placed on the port side and operated with a separate control cable in a similar manner.




Referring now to

FIG. 14

, an alternative embodiment of a sailboat


320


will be described. Attached to deck


12


is a support


321


having a track


322


to which a carriage


324


is coupled. Support


321


is coupled to deck


12


in any conventional manner. Hence, one advantage of sailboat


320


is the ease in adding support


321


and track


322


. Sailboat


320


further includes a foresail


326


having a head (not shown), a tack


328


and a clew


330


. Tack


328


is coupled to carriage


324


. Carriage


324


in turn is coupled to track


322


in a manner such that carriage


324


may slide along track


322


. In this way, carriage


324


will slide to a given position along track


322


depending on the direction of the wind. In this way, tack


328


will be positioned at a preferred location without the use of any cables or lines. Rather, the wind itself moves tack


328


to the proper position.




The head of foresail


326


may be coupled to mast


26


using any of the attachment schemes described herein. Conveniently, a pair of sheets


329


are attached to clew


330


to adjust the position of clew


330


. Optionally, track


322


includes a plurality of openings


325


that are distributed along the length of track


322


. Stops, such as pegs, may be placed in selected openings to control the length of travel of carriage


324


along track


322


or to fix its position.




For convenience of discussion, the position of tack


328


may be defined in terms of an angle lying between central axis


18


and a line extending from tack


328


to the center line of mast


26


. The length of track


322


may be adjusted (or stops may be used within openings


325


) to adjust this angle. For example, track


322


may have a length sufficient to create an angle of at least 45 degrees, as previously defined. For convenience of discussion, such an angle will hereinafter be referred to as the operating angle.




One particular advantage of sailboat


320


(as well as the other embodiments of sailboats described herein) is the ability to move the tack back to weather to expose more of the foresail. In this way, to accomplish a broad reach, the foresail may be moved so as not to have the mainsail block its wind.




Shown in

FIG. 15

is another alternative embodiment of a sailboat


327


. Rotatably coupled to deck


12


is a turret


329


. Extending from turret


329


is a frame


331


which includes a translatable arm


332


. Coupled to arm


332


is a luff cable


334


. Luff cable


334


is configured to be coupled to a foresail (not shown) similar to other embodiments described herein. As such, luff cable


334


may be attached to mast


26


according to any of the schemes described herein. Deck


12


includes a curved slot


336


for receiving an extension on frame


331


. In this way, slot


336


serves to maintain frame


331


coupled to deck


12


when forces are exerted on frame


331


by the foresail. The construction of frame


331


also serves to maintain the integrity of the frame during operation.




One particular advantage of employing turret


329


in combination with arm


332


is that two degrees of motion may be obtained, i.e., a rotational degree of motion and a translational degree of motion. In this way, luff cable


334


may be rotated and/or translated so that the position of the foresail may be varied. Turret


329


and arm


332


may be configured to operate in a manner similar to that described in U.S. Pat. No. 4,630,327, the complete disclosure of which is herein incorporated by reference.




Another advantage of employing turret


329


and arm


332


is that a large operating angle may be produced without requiring extensive equipment extending beyond deck


12


. Another advantage is that arm


332


may be retracted when turret


329


moves luff cable


334


between the port and starboard sides of the sailboat. In this way, luff cable


334


will not become engaged with or interfere with forestay


28


as the foresail is changed to an opposite side of the boat.





FIG. 16

illustrates sailboat


327


having a foresail


338


coupled to luff cable


334


. Foresail


338


includes a head


340


, a tack


342


and a clew


344


. Conveniently, mast


26


includes a track


346


which allows head


340


to be raised and lowered.




Sailboat


327


further includes a mainsail


348


which is coupled to mast


26


. Coupled to a bottom of mainsail


348


is a boom


350


. Tracks


352


and


353


are attached to deck


12


and a traveler


354


is provided on track


352


to control movement of boom


350


as is known in the art. According to the invention, a boom pole


356


extends between track


353


and boom


350


to also allow for the adjustment of the position of boom


350


. Boom pole


356


is particularly advantageous in maintaining the same spatial orientation between mainsail


348


and foresail


338


. More specifically, when sailboat


327


is moving into the wind, tack


342


and clew


344


will be positioned at a desired orientation. In many cases, it is desirable to have the tack and clew of mainsail


348


have the same relative positions. However, the head wind will tend to swing mainsail


348


(in this case, toward starboard side


22


). By employing boom pole


356


, boom


350


may be forced back toward port side


20


so that mainsail


348


will have the desired spatial orientation with foresail


338


.




Although boom pole


356


is shown as being coupled to track


353


, it will be appreciated that boom pole


356


may be coupled to other locations on sailboat


327


. Merely by way of example, boom pole


356


may be attached to the bottom of cabin


42


.




Referring now to

FIG. 17

, an alternative embodiment of a sailboat


358


will be described. Sailboat


358


includes a pair of sprit poles


360


and


362


extending from a hull of sailboat


358


. Extending between sprit poles


360


and


362


is a line


366


. Line


366


is in turn coupled to a tack


368


of a foresail


370


. In this way, the location of tack


368


may be varied by pulling on either end of line


366


.




Sprit poles


360


and


362


may be configured to be fixed relative to hull


364


or maybe extendable. In this way, the position of tack


368


relative to forepeak


16


may be varied by adjusting the amount of extension of poles


360


and


362


.




In one alternative, a fixed line may be placed between poles


360


and


362


. In this way, tack


368


may slide over the line as dictated by the direction of the wind similar to the embodiment of FIG.


14


. As another alternative, tack


368


may be directly attached to the end of either sprit pole


360


or


362


. In still another embodiment, a track may be positioned between sprit poles


360


and


362


. This may be accomplished, by placing the track between the poles while the sailboat is docked.




One particular advantage of using retractable sprit poles is that the poles may be retracted when not in use. Further, the sprit poles may be extended so that the operating angle may be as great as 45 degrees. Still further, use of sprit poles


360


and


362


allows tack


368


to be moved as close as possible to forepeak


16


without having the foresail interfere with forestay


28


when being moved to opposite sides of the sailboat.




Referring to

FIG. 18

, still another embodiment of a sailboat


372


will be described. Attached to deck


12


are a plurality of attachment points


374


that are offset from center line


18


. It will be appreciated that the number and location of attachment points


374


may vary depending on the particular need. Sailboat


372


further includes a foresail


376


having a head (not shown), a tack


378


and a clew


380


. Tack


378


is coupled to one of attachment points


374


so that tack


378


is offset from center line


18


. Depending on the desired location of foresail


376


, tack


378


may be manually attached to any one of the attachment points


374


. Conveniently, sheets or lines


382


are coupled to clew


380


to control the location of clew


380


. Although not shown, it will be appreciated that the head of foresail


376


may be coupled to mast


26


using any of the attachment schemes described herein. Preferably, the head of foresail


376


will be coupled to mast


26


using a pivotal strut as described herein.




Referring now to

FIG. 19

, an alternative embodiment of a sailboat


384


having a mast


26


will be described. The features of sailboat


384


may be used in connection with any of the sailboats described herein. Mast


26


includes a connector


386


to which a forestay (not shown) may be coupled to secure mast


26


to the sailboat as is known in the art. Also coupled to connector


386


is a halyard


388


. A line


390


passes around halyard


388


and is employed to raise a head


392


of a foresail


394


.




Coupled to mast


26


is a track


396


. Slidably coupled to track


396


are carriages


398


and


400


. Carriage


400


is pivotally coupled to an adjustable strut


402


. Strut


402


comprises a tubular section


404


for receiving a cylindrical section


406


. The amount that section


406


may be extended from section


404


is determined by a pin


408


. Section


406


includes a ring


410


which allows it to be pivotally coupled to carriage


400


. Section


404


also includes a ring


412


which is coupled to head


392


. In this way, the location of head


392


will adjust itself relative to mast


26


depending on the direction of the wind. Further, the length of strut


402


may be adjusted to further adjust the distance at which head


392


may be distanced from mast


26


. Still further, a line


414


is coupled to carriage


400


and extends around a halyard


416


on carriage


398


. In this way, carriage


400


may be raised or lowered relative to carriage


398


.




Carriage


398


is raised and lowered by a line


418


that extends around a halyard


420


. Extending between carriage


398


and ring


412


is a cable


422


. Cable


422


is provided to control the offset of foresail


394


from mast


26


. Use of cable


422


is particularly advantageous in facilitating the movement of foresail


394


between the port and starboard sides of the sailboat. In particular, when moving between the port and starboard sides, carriage


400


is lowered so that strut


402


will not engage the forestay when moving between port and starboard sides. Once on the other side of the forestay, carriage


400


is raised until cable


422


is again tensioned. In this manner, larger foresails may be provided without interfering with the forestay when changing the tack of the sail.




Mast


26


may also be accommodated with a scheme to adjust the shape of foresail


394


by adjusting its tension as illustrated in FIG.


20


. In

FIG. 20

, mast


26


is also supported by a shroud


424


on the starboard side and a shroud


426


on the port side. A pair of spreaders


428


and


430


are coupled to mast


26


to spread shrouds


424


and


426


. A block


432


is coupled to shroud


426


(it being appreciated that a similar block may be coupled to shroud


424


). A line


434


extends around block


432


and is coupled to ring


412


on strut


402


. Line


434


may be manipulated to adjust the amount of tension on the luff of foresail


394


when positioned portside. A similar scheme may be provided to tension the luff of the foresail when located on the starboard side. Line


434


is particularly advantageous in that it allows for the shape of the foresail to be adjusted merely by varying the tension in line


434


.




Referring now to

FIG. 21

, another alternative embodiment of a sailboat


436


will be described. Sailboat


436


is similar to the embodiment of FIG.


11


and includes a starboard deck track


438


and a port deck track


440


. Mast


26


includes a starboard mast track


442


and a port mast track


444


. Each of tracks


438


-


440


is provided with a carriage


446


to which a luff cable


448


may be attached to allow the foresail to be raised and lowered in a manner similar to that previously described. As illustrated in

FIG. 21

, deck tracks


438


and


440


cross each other at a center line or longitudinal axis (see axis


18


of

FIG. 1

) of deck


12


. In this way, when carriage


446


is moved to the end of its track, the foresail will be fully raised and the tack of the foresail will be directly on the center line of the sailboat.




As illustrated in

FIG. 22

, mast tracks


442


and


444


also cross each other at a point that is aligned with the center line of the sailboat. In this way, a head


450


of a foresail


452


will be aligned with the center line when the foresail is fully raised.




Turning now to

FIG. 23

, still another alternative embodiment of a sailboat


454


will be described. Sailboat


454


includes a pair of pulleys


456


and


458


which are attached to deck


12


on the center line. Mast


26


also includes a pair of pulleys


460


and


462


that are attached at a point that is aligned with the center line of the boat. In this way, two sails may be separately raised and lowered so that one sail will always remain operable. Further, when raised, each of the sails will be aligned with a center line of the sailboat.




Referring now to

FIG. 24

, an alternative embodiment of a sailboat


500


will be described. Attached to mast


26


is a foresail


502


having a head


504


, a tack


506


and a clew


508


. Head


504


is movably attached to mast


26


using an adjustable strut similar to the system shown in FIG.


12


and will not be described further. However, it will be appreciated that head


504


may be coupled to mast


26


by any of the schemes described herein. Extending from clew


508


are a pair of sheets


510


and


512


which are employed to control the location of clew


508


in a manner similar to that described with previous embodiments.




Pivotally coupled to mast


26


is a boom


514


. Extending from boom


514


is an extension


516


. Tack


506


is attached to extension


516


. In this way, the distance of tack


506


relative to mast


26


may be varied by translating extension


516


relative to boom


514


. However, it will appreciated that in some cases extension


516


may not be needed and tack


506


may be directly coupled to the end of boom


514


.




Mounted to deck


12


is a track


518


having a carriage


520


. Movement of carriage


520


along track


518


is controlled by lines


522


and


524


in association with a sheave


525


and necessary cleats. Pivotally coupled to carriage


520


and boom


514


is a boom pole


526


. Also coupled to boom


514


are lines


528


and


530


. Lines


528


and


530


pass around appropriate blocks


532


.




By providing boom


514


, tack


506


is able to be moved off of the center line of boat


500


. Boom pole


526


in combination with carriage


520


and track


518


are adjusted to hold boom


514


off of the center line. Further, lines


528


and


530


in combination with blocks


532


are employed to control the downward pressure on boom


514


. In this manner, tack


506


may be moved to either side of the boat and held in a desired position. When it is desired to change the position of tack


506


, carriage


520


is moved toward mast


26


. If needed, extension


516


may be withdrawn so that tack


506


will not interfere with forestay


28


. Optionally, lines


528


and


530


may be employed to move boom


514


to the other side of the boat. Carriage


520


is then moved away from mast


26


to hold boom


514


in the desired position.




Although boom


514


is shown as being straight in geometry, it will be appreciated that variations may be made in order to accommodate various features of boat


500


. For example, in cases where a hatch is provided on the bow of boat


500


, boom


514


may be moved vertically upward and include a dog leg so that it will not interfere with the opening of the hatch.




EXAMPLE




A Santana


23


boat was modified to include a track similar to the track of FIG.


14


and to have an adjustable strut similar to the strut of FIG.


12


. The boat was sailed into a wind of approximately 15 knots. When the operating angle of the foresail was at approximately 22 degrees, the boat was able to sail offwind by approximately 23 degrees.




Traditional sailboats are only able to sail at approximately 45 degrees offwind. Hence the boat of this example was able to improve the degree of travel into the wind by 22 degrees. Further, it is anticipated that as the operating angle is increased, the sailboats of the invention may be able to travel even closer to the direction of the wind. In this manner, the sailboats of the invention may be sailed in essentially any direction regardless of the direction of the wind.




The invention has now been described in detail for purposes of clarity and understanding. However, it will be appreciated that certain changes and modifications may be made within the scope of the invention. Therefore, the scope and content of this invention are not limited by the foregoing description. Rather, the scope and content are to be defined by the following claims.
