Referring now to the drawings, FIGS. 1A & 1B provide perspective views of an illustrative embodiment of an enclosed boat trailer 10, which may be configured to be supported by a plurality of wheels 15 for towing by a primary mover. As shown in FIG. 1B, a portion of the roof and right-side wall are removed to show an interior portion of the enclosed boat trailer 10. Another illustrative embodiment of an enclosed boat trailer 10 is shown in FIG. 1C, wherein the illustrative embodiment in FIG. 1B has a differently configured roller system 30 compared to that shown in FIG. 1C as described in further detail below.

Generally, the illustrative embodiments of an enclosed boat trailer 10 may be backed into or near a body of water for loading and/or unloading a boat 18 into the enclosed boat trailer 10. The enclosed boat trailer 10 may be configured with wide-opening, side-hinged rear doors 16 at a rear opening 14 and a roller system 30 (which may be moveable and responsive to contact with the boat hull 18a) engaged with a portion of the floor 11 of the enclosed boat trailer 10 such that the boat 18 operator may directly drive a boat 18 from the water into the enclosed boat trailer 10 without assistance from another individual. The illustrative embodiment of an enclosed boat trailer 10 may also be configured with a forward door adjacent a front portion of the enclosed boat trailer 10. It is contemplated that a forward door 17 may allow relatively easy access to an interior portion of the enclosed boat trailer 10 even when a boat 18 positioned therein.

The illustrative embodiments of an enclosed boat trailer 10 may also allow a boat 18 operator to unload a boat 18 from the trailer while inside the boat 18 and without assistance from another individual, and/or in less time and/or with less effort than compared to trailers found in the prior art. The additional time and/or personnel required when using prior art trailers may be at least due to the prior art trailer requiring a single operator to get in and out of the boat 18 various times to properly align the boat 18 with the trailer, engage the cable with the boat 18, operate the winch, manual move the boat 18 with respect to the trailer, etc. without limitation unless otherwise indicated in the following claims. Although the illustrative embodiments of an enclosed boat trailer 10 may be configured to accommodate a boat 18 that is approximately eight feet wide, other configurations, dimensions, etc. to accommodate differently sized, shaped, and/or configured boats 18 without limitation unless otherwise indicated in the following claims. The scope of the enclosed boat trailer 10 is not limited to any specific advantage over prior art boat trailers and/or shortfall of prior art boat trailers unless otherwise indicated in the following claims.

Generally, the various components of an enclosed boat trailer 10 for the illustrative embodiments thereof described in detail below (e.g., winch 14, launch assist system 20, roller system 30, structures and/or methods for engaging the roller system 30 with the floor 11, rear arms 40a, 40b, etc.) may be modular in nature such that an existing enclosed trailer of the proper dimensions and/or specifications may be converted to an enclosed boat trailer 10. Alternatively, a trailer may be configured as an enclosed boat trailer 10 initially during the manufacturing of the trailer itself without limitation unless otherwise indicated in the following claims. Accordingly, the scope of the enclosed boat trailer 10 is not limited to retrofit kits, original equipment, etc. unless otherwise indicated by the following claims, and the optimal configuration of the enclosed boat trailer 10 and various components thereof (e.g., winch 14, launch assist system 20, roller system 30, structures and/or methods for engaging the roller system 30 with the floor 11, rear arms 40a, 40b, etc.) will vary from one application to the next and may be dependent on whether the enclosed boat trailer 10 is from a retrofit of an existing trailer or configured as such from the factory.

Referring still to FIGS. 1A & 1B (and also FIGS. 2A, 2B, & 3A), an illustrative embodiment of a roller system 30 that may be used with various embodiments of an enclosed boat trailer 10 are shown in more detail. A second illustrative embodiment of a roller system 30 is shown in FIGS. 1C and 3B, wherein various components of the roller system 30 are shared between the two illustrative embodiments. However, the specific configuration, number, and/or arrangement of certain components of the roller system 30 may vary from one embodiment of an enclosed boat trailer 10 to the next, and are therefore in no way limiting to the scope of the present disclosure unless otherwise indicated in the following claims.

As shown, a portion of the bottom surface of the enclosed boat trailer 10 may be configured with a plurality of roller pairs 31 and central rollers 33 extending from the rear adjacent the rear doors 16 forward such that the roller system 30 covers over half the length of the floor 11 of the enclosed boat trailer 10. The roller system 30 may be configured with opposing rows or roller pairs 31 such that there is an approximate line of symmetry fore-to-aft along the centerline of the roller system 30 when viewed as shown in FIG. 3 and left-to-right when viewed as shown in FIGS. 2A & 2B. It is contemplated that during use, one roller pair 31 in the first row of roller pairs 31 will engage a first side of the boat hull 18a and a corresponding roller pair 31 in the second row of roller pairs 31 will engage a second side of the boat hull 18a at the same or approximately the same lengthwise position on the boat hull 18a as the first roller pair 31. In other illustrative embodiments of the enclosed boat trailer 10 not pictured herein, the roller system 30 may be configured differently than roller pairs 31 arranged in opposing rows and may instead be configured merely as opposing rollers without limitation unless otherwise indicated in the following claims.

The optimal configuration and/or dimensions of the roller system 30 (e.g., width, length, distance from rear doors 16, number of roller pairs 31, number of center rollers 33, number of roller pairs 31 engaged with a given roller mounting beam 32, rows, distance from the front of the enclosed boat trailer 10, etc.) will vary from one application of the enclosed boat trailer 10 to the next, and depend at least in part on the type, size, and configuration of the boat 18 to be positioned in the enclosed boat trailer 10. Accordingly, the scope of the enclosed boat trailer 10 is not limited by the specific configuration and/or dimensions of the roller system 30 unless otherwise indicated in the following claims.

Referring now to FIGS. 4-6, the illustrative embodiments of a roller system 30 may be comprised of a plurality of roller pairs 31, wherein each roller pair 31 may include two roller wheels 31a on opposite ends of a roller axle 31b. The roller wheels 31a may be free to rotate with respect to the roller axle 31b. The roller axle 31b may be pivotally engaged with a roller mounting beam 32, and a single roller mounting beam 32 may provide an engagement point for a plurality of roller axles 31b. Generally, the roller axle 31b may pivot with respect to the roller mounting beam 32 in such a manner as to account for a predetermined amount of rolling motion and/or roll misalignment of a boat 18 with respect to the enclosed boat trailer 10, and it may also account for a predetermined amount of yaw motion and/or yaw misalignment, but the specific configuration, the amount and/or direction of relative motion and/or misalignment between the boat 18 and the enclosed boat trailer 10 accommodated, and/or pivotal limits between the roller axle 31b and roller mounting beam 32 are in no way limiting unless otherwise indicated in the following claims.

As shown, in an illustrative embodiment the two rearward roller mounting beams 32 may be engaged with six roller pairs 31 (and consequently six roller axles 31b) generally placed in relatively close proximity to one another along the length of the roller mounting beam 32. In FIG. 6, the illustrative embodiment of the two forwardmost roller mounting beams 32 may be engaged with two roller pairs 31 (and consequently two roller axles 31b), wherein each roller pair 31 is generally placed at either end of the roller mounting beam 32. The two forwardmost roller mounting beams 32 may also be spaced from one another by a distance less than the corresponding distance between corresponding roller mounting beams 32 positioned more rearwardly. Such a configuration may allow the roller pairs 31 toward the front of the enclosed boat trailer 10 to better accommodate portions of the boat hull 18a adjacent the bow and roller pairs 31 toward the rear of the enclosed boat trailer 10 to better accommodate portions of the boat hull 18a adjacent the stern without limitation unless otherwise indicated in the following claims.

Additionally or alternatively, one or more roller axles 31 may be engaged with a roller mounting beam 32 via a mounting beam rocker, as shown at least in FIG. 5. The mounting beam rocker 32 may be pivotally engaged with the roller mounting beam 32 in a manner to account for a determined amount of pitching motion and/or pitch misalignment of a boat 18 with respect to the enclosed boat trailer 10. Finally, the roller mounting beam 32 may be engaged with the floor 11 of the enclosed boat trailer 10 such that it is pivotal with respect to the enclosed boat trailer 10 and in such a manner to account for a determined amount of pitching motion and/or pitch misalignment of a boat 18 with respect to the enclosed boat trailer 10. However, the specific configuration, the amount and/or direction of relative motion and/or misalignment between the boat 18 and the enclosed boat trailer 10 accommodated, and/or pivotal limits between the mounting beam rocker 32a and roller mounting beam 32 and/or between the roller mounting beam 32 and floor 11 of the enclosed boat trailer 10 are in no way limiting unless otherwise indicated in the following claims.

The roller system 30 may also include one or more central rollers 33. It is contemplated that a central roller 33 may be configured to engage a keel formed in the boat hull 18a. A first central roller 33 may be positioned at the rear of the enclosed boat trailer 10 just forward of the rear opening 14 and may be positioned as low to the floor 11 as possible, as the rearward central roller 33 may serve as the first contact point of the boat 18 with any portion of the enclosed boat trailer 10 during loading. That central roller 33 may serve as a guide for the boat 18 when loading the boat 18 onto the enclosed boat trailer 10 and may help to ensure proper positioning between the boat 18 and enclosed boat trailer 10 and/or help to protect the keel or other portions of the boat hull 18a without limitation unless otherwise indicated in the following claims. Another central roller 33 may be positioned toward the front of the enclosed boat trailer 10 and may be elevated above the floor 11 and may also be configured to engage the keel of the boat hull 18a. In an illustrative embodiment, the forwardmost central roller 33 may be positioned adjacent a winch 40 positioned toward a forward portion of the enclosed boat trailer 10. Additional or fewer central rollers 33, differently configured and/or positioned central rollers 33, etc. may be used with the roller system 10 without limitation unless otherwise indicated in the following claims.

Although a nearly infinite number of structures and/or methods for engaging a roller system 30 with the floor 11 of the enclosed boat trailer 10 may be used, an illustrative embodiment thereof will now be described in detail with the understanding that the various details and/or components thereof are not to be regarded as limiting unless otherwise indicated in the following claims. It is contemplated that for many applications it may be advantageous to configure the roller system 30 to be as low-profile as possible so as to accommodate a relatively taller boat 18 and/or to reduce the overall height of the enclosed boat trailer 10 without limitation unless otherwise indicated in the following claims. It is further contemplated that an enclosed boat trailer 10 configured as such from the factory may use other structures, methods, and/or components to provide a roller system 30 on the floor 11 of the enclosed boat trailer 10 than those described herein, and such embodiments of an enclosed boat trailer 10 are within the scope of the enclosed boat trailer 10 unless otherwise indicated in the following claims.

Referring specifically to FIGS. 5 & 6, each roller support beam 32 may be pivotally engaged with a lower support base 36, wherein the pivot point of the roller support beam 32 with respect to the lower support base 36 may be generally at the center of the roller support beam 32 with respect to its length, but which may be differently configured in other embodiments of the enclosed trailer 10 without limitation unless otherwise indicated in the following claims. A coupling member 35 may be configured to accommodate the pivotal engagement between a roller support beam 32 and a lower support base 36, wherein the lower support base 36 may be selected engaged with the floor 11 as described in further detail below.

An illustrative embodiment of a coupling member 35 may be comprised of a first yoke 35a that engages a roller support beam 32 and generally faces upward and a second yoke 35b that engages the lower support base 36 and generally faces downward. The first yoke 35a and second yoke 35b may be formed as one integral unit and may be rotationally offset from one another by 90 degrees. The roller support beam 32 may be pivotally engaged with the first yoke 35a such that the pivot point between the roller support beam 32 and first yoke 35a allows for a predetermined amount of angular motion between the roller support beam 32 and coupling member 35 (and consequently between the roller support beam 32 and lower support base 36 and between the roller support beam 32 and floor 11 of the enclosed boat trailer 10). The optimal amount of allowable relative motion therebetween will vary from one application of enclosed boat trailer 10 to the next and is therefore in no way limiting to the scope thereof unless otherwise indicated in the following claims. Additionally, other structures and/or methods may be used to engage a roller support beam 32 with a lower support base 36 without limitation unless otherwise indicated in the following claims.

One or more lower plates 34 may be positioned on the floor 11 of the enclosed boat trailer 10, and each lower support base 36 may be positioned on the upper surface of a lower plate 34. The lower plate 34 may provide added rigidity, structural integrity, ease of use, longevity, or any other suitable purpose without limitation unless otherwise indicated in the following claims. Cross plates 34a may be engaged with various lower plates 34 along the length thereof for additional support and/or structure integrity without limitation unless otherwise indicated in the following claims. Generally, the lower plates 34 and lower support bases 36 may be configured such that the opposing rows of roller pairs 31 may be adjusted to accommodate boats 18 having different dimensions and/or configurations. Accommodating for different boat 18 and/or boat hull 18a widths may be accomplished by adjusting the lateral position of the lower support base 36 (i.e., the distance of the lower support base 36 from the centerline of the floor 11).

A U-bolt 37 may be positioned under the floor 11 with the studs extending through the floor 11 and on either side of the lower support base 36. A U-bolt plate 38 may be configured with corresponding apertures to accept the studs of the U-bolt 37, such that the lower support base 36 is effectively clamped to the floor 11 via the U-bolt 37 and U-bolt plate 38. In the illustrative embodiments pictured herein, the lower support base 36 may be configured as a length of box-iron that may fit between the studs of the U-bolt 37. By loosening the U-bolt plate 38, the lower support base 36 (and consequently any roller mounting beam 32, roller pair 31, coupling member 35, etc. engaged therewith) may slide laterally along the floor 11 and with respect to the lower plate 34, U-bolt 37, and U-bolt plate 38 to the desired position. When in the desired position, the U-bolt plate 38 may be tightened to the lower support base 36 thereby securing the position of the lower support base 36 on the floor 11. As shown, an illustrative embodiment of an enclosed boat trailer 10 may employ a plurality of lower support bases 36 and corresponding U-bolts 37 and U-bolt plates 38(one each, respectively, for each roller mounting beam 32), but the specific number, position, configuration, etc. of those components is not limiting unless otherwise indicated in the following claims.

Although specific and detailed reference has been made herein to a lower plate 34, lower support base 36, U-bolt 37, U-bolt plate 38, and coupling member 35 for providing a roller system 30 that allows for adjusting the lateral distance between opposing rows of roller pairs 31, any suitable structure and/or method for adjusting that distance may be used with various embodiments of the enclosed boat trailer 10 without limitation unless otherwise indicated in the following claims. Indeed, it is contemplated that enclosed boat trailers 10 configured as such from the factory may not require at least the lower plates 34, lower support base 36, U-bolt 37, and/or U-bolt plate 38 depending on the specific configuration, or may utilize other structures providing at least the same features and/or functionality of those components as disclosed herein. Such embodiments are fully within the scope of the enclosed boat trailer 10 without limitation unless otherwise indicated in the following claims.

As is evident from contrasting the illustrative embodiment of an enclosed boat trailer 10 as shown in FIGS. 1B & 3A with the illustrative embodiment shown in FIGS. 1C & 3B, various configurations of a roller system 30 may be used. By way of illustration, and without limitation unless otherwise indicated in the following claims, the illustrative embodiment shown in FIGS. 1B & 3A may be comprised of three roller mounting beams 32 on each side of the centerline of the enclosed boat trailer 32. The two rearward-most roller mounting beams 32 on a given side of the centerline (wherein each rearward roller mounting beam 32 may be engaged with six roller pairs 31) may be horizontally spaced from the corresponding roller mounting beam 32 on the other centerline by substantially the same distance. The forward-most roller mounting beam 32 on a given side of the centerline (wherein each forward roller mounting beam 32 may be engaged with two roller pairs 31) may also be horizontally spaced from the corresponding roller mounting beam 32 on the other side of the centerline by substantially the same distance. However, the distance between the two corresponding forward-most roller mounting beams 32 may be less than the distance between two corresponding rearward-most roller mounting beams 32 without limitation unless otherwise indicated in the following claims. It is contemplated that such a configuration may accommodate a relatively conventional boat hull 18a configuration having a relatively narrower width adjacent the bow compared to the width adjacent the stern.

By way of illustration, and without limitation unless otherwise indicated in the following claims, the illustrative embodiment shown in FIGS. 1C & 3B may be comprised of four roller mounting beams 32 on each side of the centerline of the enclosed boat trailer 32 and two center rollers 33 positioned adjacent the rear opening 14. Each rearward-most roller mounting beam 32 on a given side of the centerline (wherein each rearward roller mounting beam 32 may be engaged with six roller pairs 31) may be horizontally spaced from the corresponding roller mounting beam 32 on the other centerline by substantially the same distance. The two intermediate roller mounting beams 32 on a given side of the centerline (wherein each intermediate roller mounting beam 32 may be engaged with six roller pairs 31) may be horizontally spaced from the corresponding roller mounting beam 32 on the other centerline by substantially the same distance. However, the distance between the two corresponding rearward-most roller mounting beams 32 may be less than the distance between two corresponding intermediate roller mounting beams 32 without limitation unless otherwise indicated in the following claims. The forward-most roller mounting beam 32 on a given side of the centerline (wherein each forward roller mounting beam 32 may be engaged with two roller pairs 31) may also be horizontally spaced from the corresponding roller mounting beam 32 on the other side of the centerline by substantially the same distance. However, the distance between the two corresponding forward-most roller mounting beams 32 may be less than the distance between two corresponding intermediate roller mounting beams 32 and may be greater than the distance between the two corresponding rearward-most roller mounting beams 32 without limitation unless otherwise indicated in the following claims. It is contemplated that such a configuration may accommodate a relatively conventional boat hull 18a configuration having a relatively narrower width adjacent the bow compared to the width adjacent the stern.

Referring now to FIG. 8, an illustrative embodiment of an enclosed boat trailer 10 may be configured with a winch 40, wherein the winch 40 may be positioned generally toward the front of the enclosed boat trailer 10 and ahead of the roller system 30. The winch 40 may be configured with a spool 42 and cable 44, wherein one end of the cable 44 may be configured with a hook to attach to an eyelet engaged with the front of a boat 18. The winch 40 may be powered, wherein the power control may be activated and deactivated remotely, and the winch 40 may simultaneously be configured to allow for manual operation of so desired by the user. Generally, the winch 40 may be used and configured to pull the boat 18 into the enclosed boat trailer 10 and over the roller system 30. It is contemplated that remote activation and/or deactivation of the winch 40 may further facilitate safe and efficient loading and/or unloading of a boat 18 from the enclosed boat trailer 10 by a single operator, wherein the prior art would oftentimes require at least two operators to perform the same task or require a single operator to spend considerably more time than compared to using the enclosed boat trailer 10.

Referring now to FIGS. 9 & 10, an illustrative embodiment of the enclosed boat trailer 10 pictured herein may be configured with a launch assist system 20. An illustrative embodiment of a launch assist system 20 may be comprised of a wheel 24, wherein the wheel 24 may be configured such that it is biased against a portion of the hull of a boat 18 positioned within the enclosed boat trailer 10. The wheel 24 may be engaged with a rotational power source, such as an electric motor 26. When the rotational power source is energized, the wheel 24 may turn, thereby urging the boat 18 in one direction or the other (i.e., into or out of the enclosed boat trailer 10) depending on the direction of rotation of the wheel 24.

The wheel 24 may be mounted on a pivoting arm 21, wherein a first end of the pivoting arm 21 may be pivotally engaged with a portion of the enclosed boat trailer 10 and wherein the pivoting arm 21 may be biased in a direction toward the hull of the boat 18 via a biasing member 22 (e.g., mechanical spring, air spring, etc.) acting on the arm 21. In this manner adequate engagement between the surface of the wheel 24 and the hull of the boat 18 may be ensured while simultaneously allowing the position of the wheel 24 to adapt to the shape of the hull, the position of the boat 18 with respect to the enclosed boat trailer 10, and/or to different boats 18. It is contemplated that the launch assist system 20 may aide in initiating motion of the boat 18 out of the enclosed boat trailer 10 (such as when launching the boat 18 in a body of water) and may also aide in ensuring the boat 18 is properly positioned within the enclosed boat trailer 10 when loading the boat 18 (which may be accomplished in or with cooperation with the winch 40 as previously described above). The launch assist system 20 may be used with any suitable embodiment of an enclosed boat trailer 10 as disclosed herein or may be omitted in certain embodiments thereof without limitation unless otherwise indicated in the following claims.

Referring now to FIGS. 11A-11D, an illustrative embodiment of an enclosed boat trailer 10 may be configured with an extendable rear arm 40a, 40b on either side of the enclosed boat trailer 10 at the rear portion thereof. The extendable arms 40a 40b may be configured to help guide a boat 18 into and onto the roller system 30 and into the enclosed boat trailer 10 as described in further detail below.

The illustrative embodiment of an extendable arm 40a, 40b may be configured with a horizontal portion 42 and an upper portion 44. Generally, a right rear arm 40a may be positioned on the right side of the rear opening 14 of the enclosed boat trailer 10 and a left rear arm 40b may he positioned on the left side thereof. The horizontal portion 42 may be engaged with the floor 11 of the enclosed boat trailer 10 and angled with respect to the longitudinal axis thereof. In an illustrative embodiment the horizontal portions may be engaged with a cross plate 34a for additional rigidity and/or structural support without limitation unless otherwise indicated in the following claims. Generally, the upper portion 44 may extend upward and at an angle from the horizontal portion 42. In an illustrative embodiment pictured herein, the upper portion 44 may be engaged with the horizontal portion 42 such that they are generally perpendicular with respect to one another and form an L-shaped member, but other angles and/or configurations may be used without limitation unless otherwise indicated in the following claims. The horizontal and upper portions 42, 44 may be separately formed and then engaged with one another or integrally formed as one piece without limitation unless otherwise indicated in the following claims.

The horizontal portion 42 may include a horizontal extender 42a, such that the length of the horizontal portion 42 may be increased and/or decreased within a certain predetermined range. Similarly, the upper portion 44 may include an upper extender 44a such that the length of the upper portion 44a may be increased and/or decreased within a certain predetermined range. In an illustrative embodiment, both the horizontal extender 42a and upper extender 44a may be configured as telescoping box irons, but any suitable structure and/or method to vary the length of either the horizontal portion 42 or upper portion 44 may be used without limitation unless otherwise indicated in the following claims.

As best shown in FIGS. 11C & 11D, the extendible arms 40a, 40b may be configured with a contact portion 46 on an upper of the upper portion 44, wherein the contact portion 46 may be configured to engage a portion of the boat 18 without damaging the boat 18 and/or any component of the enclosed boat trailer 10. That is, the contact portion 46 may be configured to allow slideable engagement with the boat hull 18a or other portions of the boat 18 during the loading and entry process. Accordingly, in an illustrative embodiment the contact portion 46 may be constructed of a polymer and/or plastic material, such as polytetrafluoroethylene, polypropylene, polyester, polyvinyl chloride, other synthetic materials, other natural materials, and/or combinations thereof without limitation unless otherwise indicated in the following claims. Each contact portion 46 may be configured to extend from the upper portion 44 of the respective rear arm 40a, 40b forward through the rear opening 14 so as to prevent and/or mitigate damage that may be caused through unwanted contact of the boat 18 with a portion of the enclosed boat trailer 10 adjacent the rear opening 14 thereof without limitation unless otherwise indicated in the following claims.

It is contemplated that during loading of a boat 18, the horizontal extenders 42a may be extended away from the rear opening 14 of the enclosed boat trailer 10, as shown in FIGS. 11B, 11C, & 11D. The angle of the horizontal portions 42 with respect to the centerline of the enclosed boat trailer 10 provides an angled guide for the boat 18 to aide the boat 18 operator in centering the boat 18 with respect to the roller system 30 and/or enclosed boat trailer 10, wherein the opening between the upper portions 44 and/or contact portions 46 may be wider than the rear opening 14 of the enclosed boat trailer 10 and wherein the upper portions 44 and/or contact portions 46 may extender rearward beyond the rear opening 14. The horizontal extenders 42a may be retracted when not in use such that the rear doors 16 may be fully closed without interference from the rear arms 40a, 40b. The horizontal extenders 42a may also be extended during unloading of a boat 18 without limitation unless otherwise indicated in the following claims.

The upper extenders 44a may be extended and/or retracted for various reasons, including but not limited to account for boats 18 of different configurations (e.g., hull widths, heights, shapes, etc.) and ensure that the contact portion 46 is the only touch point between the boat 18 and the rear arms 40a, 40b. The upper extenders 44a may also be extended and/or retracted to account for the angle of the enclosed boat trailer 10 and roller system 30 (that is, the pitch) with respect to the boat 18, which may vary at least depending on the terrain on which the enclosed boat trailer 10 is positioned during loading and/or unloading.

Accordingly, via the horizontal extender 42a, the distance from and relative angle with respect to the enclosed boat trailer 10 to which the extendable arms 40a, 40b extend may be adjustable, and the optimal distance and angle thereof may vary from one application of the enclosed boat trailer 10 to the next and may be dependent at least on the configuration of the boat 18 for which the enclosed boat trailer 10 is designed. The height of the extendable arms 40a, 40b (and. consequently the height of any contact portion 46 and/or other component engaged therewith) may also be adjustable. Accordingly, the specific configuration, dimensions, angles, etc. of the extendable arms 40a, 40b in no way limits the scope of the enclosed boat trailer 10 unless otherwise indicated in the following claims.
