Certain disclosed embodiments relate to the field of boating and, more particularly, to systems and methods for righting a capsized watercraft.
Lifting and righting a capsized boat in the water, especially deep water, is physically challenging or impossible for many boaters. Even if the boat can be righted, the process often allows a large volume of water to enter the boat. Typically, when a boat overturns or capsizes, the boat partly fills with water and at least one side of the boat is underwater. Unless the boater is capable of lifting most of the boat above the water before turning it over, water typically pours over the lowermost side and into the boat during the righting process. Boats that have a generally low center of gravity, such as canoes or kayaks, typically float very low in the water when capsized. Currently available systems and techniques for righting a capsized boat require permanent modifications to the boat and/or the onboard storage of additional equipment, and most result in a substantial volume of water entering the boat. Thus, there is a need in the art for improved systems and methods for righting a capsized watercraft.
A system for righting a capsized boat is described. According to various embodiments, the system includes a primary gunwale float having at least one selectively openable loop that is sized and shaped to releasably secure the primary gunwale float near a distal gunwale of a boat. The primary gunwale float defines a bladder pouch for supporting a selectively inflatable bladder. The primary gunwale float lifts at least a portion of the distal gunwale at least partially above the surface of a body of water and thereby impedes the entry of water into the boat when at least a portion of a proximal gunwale of the boat is lifted at least partly above the surface by a boater.
The boat may include a distal side rail attached near the distal gunwale. The at least one selectively openable loop is sized and shaped to releasably secure the primary gunwale float to the distal side rail.
The bladder may include a valve extending through an opening in the bladder pouch.
The primary gunwale float may include a top layer, a bottom layer, and an intermediate layer, wherein the top layer and the intermediate layer define the bladder pouch.
The primary gunwale float may further include an open end and a closed end, wherein the top layer and the bottom layer define a long pouch that extends from the open end to near the closed end and is sized and shaped to releasably receive a part of a paddle.
The system may also be used to facilitate the entry of a person from the water into a righted boat. The system may include an outrigger comprising the part of a paddle inserted into the long pouch of the primary gunwale float, wherein the selectively inflatable bladder is sized and shaped, when inflated, to releasably secure the long pouch to the part of a paddle. The system may also include at least one strap for releasably securing the outrigger to at least one thwart of the righted boat, such that the outrigger supports a person climbing out of the water and into a righted boat.
The primary gunwale float may have a bottom layer and a top layer, a first edge and a generally opposing second edge. The primary gunwale float may further include (1) a top elongate fastener oriented lengthwise along and near the first edge and attached to the top layer and (2) a bottom elongate fastener oriented lengthwise along and near the second edge and attached to the bottom layer, wherein the primary gunwale float is sized in width to facilitate the mating and releasable attaching of the top and bottom elongate fasteners when the primary gunwale float is wrapped around a generally cylindrical support on the boat.
The system may further include a secondary gunwale float having at least one secondary selectively openable loop that is sized and shaped to releasably secure the secondary gunwale float near a distal gunwale of a boat, wherein the secondary gunwale float defines a secondary bladder pouch for supporting a selectively inflatable secondary bladder. The secondary gunwale float may lift at least a portion of the distal gunwale at least partially above the surface of a body of water and thereby impedes the entry of water into the boat when at least a portion of a proximal gunwale of the boat is lifted at least partly above the surface by a boater.
The primary gunwale float and the secondary gunwale float may cooperate to lift at least a portion of the distal gunwale.
The primary gunwale float and the secondary gunwale float may be spaced apart along the distal gunwale.
The boat may include a distal side rail attached near the distal gunwale. The at least one secondary selectively openable loop may be sized and shaped to releasably secure the secondary gunwale float to the distal side rail.
The secondary bladder includes a secondary valve extending through a secondary opening in the secondary bladder pouch.
The secondary gunwale float has a secondary bottom layer and a secondary top layer, a secondary first edge and a generally opposing secondary second edge. The secondary gunwale float may further include (1) a secondary top elongate fastener oriented lengthwise along and near the secondary first edge and attached to the secondary top layer and (2) a secondary bottom elongate fastener oriented lengthwise along and near the secondary second edge and attached to the secondary bottom layer, wherein the secondary gunwale float is sized in width to facilitate the mating and releasable attaching of the secondary top and bottom elongate fasteners when the secondary gunwale float is wrapped around a generally cylindrical support on the boat.
The secondary gunwale float comprises a secondary top layer, a secondary bottom layer, and a secondary intermediate layer, wherein the secondary top layer and the secondary intermediate layer define the secondary bladder pouch.
The secondary gunwale float further includes a secondary open end and a secondary closed end, wherein the secondary top layer and the secondary bottom layer define a secondary long pouch that extends from the secondary open end to near the secondary closed end and is sized and shaped to releasably receive a part of a paddle.
The system may be used to facilitate the entry of a person from the water into a righted boat. The system may include a secondary outrigger comprising the part of a paddle inserted into the secondary long pouch of the secondary gunwale float, wherein the secondary selectively inflatable bladder is sized and shaped, when inflated, to releasably secure the secondary long pouch to the part of a paddle. The system may also include at least one secondary strap for releasably securing the secondary outrigger to at least one thwart on the righted boat, such that the secondary outrigger supports a person climbing out of the water and into a righted boat.
In a related aspect, a method of righting a capsized boat is described. The method may include the steps of (1) providing a primary gunwale float having at least one selectively openable loop, the primary gunwale float defining a bladder pouch for supporting a selectively inflatable bladder; (2) inflating the selectively inflatable bladder; (3) attaching the at least one selectively openable loop to a boat on or near a distal gunwale of the boat; and (4) lifting a proximal gunwale of the boat above the surface of the water, while the primary gunwale float lifts at least a portion of the distal gunwale at least partially above the surface and thereby impedes the entry of water into the boat, until the boat is righted.
Where the boat includes a distal side rail mounted near the distal gunwale, the step of attaching may include fastening the at least one selectively openable loop to the distal side rail.
Where the primary gunwale float comprises a top layer, a bottom layer, and an intermediate layer, the top layer and the intermediate layer define the bladder pouch, the primary gunwale float further includes an open end and a closed end, at least a portion of the top layer and the bottom layer define a long pouch that extends from the open end to near the closed end, and the method of righting may further include a supplemental method of facilitating the entry of a person from the water into a righted boat. The supplemental method may include the steps of (a) inserting a part of a paddle into the long pouch; (b) inflating the selectively inflatable bladder to releasably secure the long pouch to the part of a paddle, to form an outrigger; (c) securing the outrigger to at least one thwart of the righted boat; and (d) using the outrigger to climb out of the water and into the righted boat.
The method may further include the steps of: (5) providing a secondary gunwale float having at least one secondary selectively openable loop the secondary gunwale float defining a secondary bladder pouch for supporting a selectively inflatable secondary bladder; (6) inflating the selectively inflatable secondary bladder; (7) attaching the at least one secondary selectively openable loop to a boat on or near the distal gunwale of the boat, spaced apart from the primary gunwale float; and (8) lifting a proximal gunwale of the boat above the surface of the water, while the primary gunwale float and the secondary gunwale float cooperate to lift at least a portion of the distal gunwale at least partially above the surface and thereby impedes the entry of water into the boat, until the boat is righted.
Where the boat includes a distal side rail mounted near the distal gunwale, the step of attaching may include fastening the at least one secondary selectively openable loop to the distal side rail.

It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
As used herein, the term “facilitate” means to aid, assist, or make easier. The term “impede” means to interfere with, hinder, or delay the progress.
As used herein, the terms “proximal” and “distal” are used to describe items or portions of items that are situated closer to and away from, respectively, a user or operator. Thus, for example, the side of an item nearest a person may be referred to as the proximal side, whereas the generally opposing side or far side may be referred to as the distal side.
The terms watercraft, vessel, and boat are used herein in the broadest sense. Those of ordinary skill will understand that the term watercraft may be used to describe and encompass any of a variety of vessels that travel on water, including but not limited to a boat, canoe, kayak, dinghy, skiff, dory, flat-bottomed boat, bass boat, inflatable boat, sailboat, paddle boat, and personal water craft of all kinds. Although the various embodiments are described with reference to a canoe or kayak, the assemblies and systems described herein may be used with any type of watercraft.
Watercraft are described using nautical jargon, some of which is used herein. The front of a boat is referred to as the bow; the rear is the stern. For a boater facing toward the bow, the right side of the boat is called the starboard side; the left is the port side. Gunwale refers to the upper or top edge of the side of a boat. A boat may include one or more handles, short rails, or longer side rails running along or mounted near the gunwales. A thwart refers to a cross beam or strut that spans the width of the boat, between the gunwales or sides of the boat. A thwart may be used as a handle, may include a seat, and may be covered by one or more cushions. A boat may have several thwarts, such as a canoe which typically has a stern thwart, a center or midship thwart, and a bow thwart.
A boat such as a sailboat or a kayak may have a top surface called the deck. The cockpit of a kayak refers to the place where the boater sits. The coaming is a raised structure or rim that surrounds an opening, such as the cockpit of a kayak. A paddle, in general, has a grip, a shaft, a throat (near where the shaft meets the blade), and a blade that terminates or ends at the tip. A single-blade paddle generally has a grip or handle at the proximal end and a blade at the distal end. The grip or handle of a two-blade paddle is near the middle of the shaft, which supports paddle blades on both ends.
Although the various embodiments are described with reference to boating and watercraft, the assemblies and systems described herein may be used with any of a variety of activities and things.
The boater 80, as shown, may begin to right the boat 10 by raising the center cushion 65, thereby lifting the proximal gunwale 41 out of the water while the primary gunwale float 200 lifts at least a portion of the distal gunwale 49 above the water surface 90. In this manner, the boat 10 can be righted with minimal intrusion of water.
According to another embodiment, the system 100 may include both a primary gunwale float 200 and a secondary gunwale float 400, as shown in
The primary gunwale float 200 may include at least one selectively openable loop or other means for attaching the float 200 the side rail or other part of a boat.
The primary gunwale float 200 may be generally rectangular in overall shape and may include a bottom layer 210 and a generally opposing top layer 220. According to various embodiments, the float 200 may also include an intermediate layer 215 (as shown in
The primary gunwale float 200 may define a bladder pouch 320 that is sized and shaped to support a selectively inflatable bladder 330. The bladder 330 may include an inflation valve 332 positioned in a filler tube that extends through an opening 335 in the top layer 220. The valve 332 may be a three-part two-port check valve, like the kind used for inflatable boats, mattresses, pool toys and the like, to prevent unintended deflation. The opening 335 may be a simple eyelet and may be reinforced by a grommet, as shown. The bladder pouch 320 may be defined by the top surface 220 and the intermediate layer 215 (shown graphically in
The primary gunwale float 200 may further include a long pouch 300. The long pouch 300, as shown in
Referring again to
As described herein, the long pouch 300 is optional and not a necessary element of the primary gunwale float 200 in performing its function of lifting one of the gunwales during the righting of a capsized boat. In this aspect, one embodiment of the primary gunwale float 200 includes only a bladder pouch 320 defined by two layers of fabric. Referring to
The system 100 may include one or more secondary floats, depending on the size, shape, and weight of the watercraft to be righted. As shown in
The secondary gunwale float 400 may or may not have the same construction and features as the primary gunwale float 200. Both floats 200, 400 may be releasably attached to the boat 10 near the distal gunwale 49. The floats 200, 400 may be attached to and spaced apart along the distal side rail 59, as shown. When attached and inflated, the floats 200, 400 may be sized and shaped to lift at least a portion of the distal gunwale 49 above the water surface 90 to impede water intrusion during the righting process.
The secondary gunwale float 400 may include at least one selectively openable loop or other means for attaching the float 400 the side rail or other part of a boat.
The secondary gunwale float 400 may be generally rectangular in overall shape and may include a secondary bottom layer 410 and a generally opposing secondary top layer 420. According to various embodiments, the float 400 may also include a secondary intermediate layer (similar to the one shown in
As shown in
The secondary gunwale float 400 may further include a secondary long pouch 500. The secondary long pouch 500, as shown in
As described herein, the secondary long pouch 500 is optional and not a necessary element of the secondary gunwale float 400 in performing its function of lifting one of the gunwales during the righting of a capsized boat. In this aspect, one embodiment of the secondary gunwale float 400 includes only a secondary bladder pouch 520 defined by two layers of fabric. Referring to
Referring again to
In use, the vessel righting system 100 facilitates the righting of a capsized watercraft 10 by a person or boater 80, typically in deep water. When capsized, one or both gunwales 41, 49 may lie below the surface 90 of the water. As illustrated in
When a watercraft is capsized, the boater 80 may begin, according to an exemplary method, by removing the primary gunwale float 200 from its storage location, which may be the center cushion 65. Referring to
The bladder 330 in the primary gunwale float 200 may then be manually inflated by the boater 80 using the valve 332. After inflation, the float 200 may then be attached to the boat near one of the gunwales (which will become the distal gunwale 49 when the boater 80 later moves to the other side of the boat) using at least one of the selectively openable loops 270, 280. The primary gunwale float 200 may be attached to the side rail 59 if one is present.
After the primary gunwale float 200 is attached, the boater 80 may then move around to the other side of the boat (which will be the near side or proximal gunwale 41) and begin lifting the boat 10 above the surface 90 of the water, as illustrated in
The system 100, as described herein, may include one or more secondary gunwale floats 400. The boater 80 may use a secondary gunwale float 400 by first removing it from its storage location, which may be the bow cushion 62. Referring to
The secondary bladder 530 in the secondary gunwale float 400 may then be manually inflated by the boater 80 using the secondary valve 532. After inflation, the secondary gunwale float 400 may then be attached to the boat near one of the gunwales (which will become the distal gunwale 49 when the boater 80 later moves to the other side of the boat) using at least one of the secondary selectively openable loops 470, 480. The secondary gunwale float 400 may be attached to the side rail 59 if one is present. The secondary gunwale float 400 may be positioned so that it is spaced apart from the primary gunwale float 200 along the distal gunwale 49 or side rail 59.
After the secondary gunwale float 400 is attached, the boater 80 may then move around to the other side of the boat (which will be the near side or proximal gunwale 41) and begin lifting the boat 10 above the surface 90 of the water, as illustrated in
After righting the boat, the boater 80 is typically still in the water. In another aspect of the embodiments described herein, the boater 80 may use one or more gunwale floats as part of another or supplemental method of climbing out of the water and into the righted boat. In this method, the boater 80 may detach one or both of the floats 200, 400 from the distal gunwale 49 of the boat.
For example, the boater 80 may detach the primary gunwale float 200 from the distal side rail 59 and deflate the bladder 330. The blade or other portion of a paddle 70 may be inserted into the long pouch 300 to that the blade is positioned against or behind the bladder pouch 320. The bladder 330 may then be inflated manually using the valve 332 until the bladder pouch 320 presses against the blade or other portion of the paddle 70, thereby helping to secure the paddle 70 inside the long pouch 300. In this aspect, the inflated gunwale float 200 secured to the paddle 70 may act as an outrigger 600, as shown in
Once inside the boat, the boater 80 may then detach the floats 200, 400, deflate the bladders 330, 530, and store the floats for later use. For example, the floats 200, 400 may be secured around one of the thwart cushions, using the elongate fasteners to secure the first edge to the second edge.
Although several embodiments have been described herein, those of ordinary skill in art, with the benefit of the teachings of this disclosure, will understand and comprehend many other embodiments and modifications for this technology. The invention therefore is not limited to the specific embodiments disclosed or discussed herein, and that may other embodiments and modifications are intended to be included within the scope of the appended claims. Moreover, although specific terms are occasionally used herein, as well as in the claims that follow, such terms are used in a generic and descriptive sense only and should not be construed as limiting the described invention or the claims that follow.
The present application claims the benefit of and priority to U.S. Provisional Application 62/569,274 filed Oct. 6, 2017, and entitled, “Watercraft Entry and Righting Systems and Methods,” which is incorporated herein by reference in its entirety.
