DETAILED DESCRIPTION OF THE DRAWINGS

(18) FIG. 1 illustrates an embodiment of an inflatable shuttle boat 100 from the side. A seat tube 200 is longer than an exterior buoyancy tube 300. Seat tube 200 and exterior buoyancy tubes 300 connect together to form a prow 400, which is raised up at an angle θ away from the water, to assist in fluid dynamics while inflatable shuttle boat 100 is being towed. FIG. 2 illustrates the same embodiment in a line drawing, with angle θ depicted at prow 400. Angle θ allows boat 100 to be towed more effectively, assisting towing via fluid dynamics for less friction and a smoother ride experience.

(19) FIG. 3 illustrates prow 400 in an expanded view for easier visibility of an underside panel 700 and angle θ. Underside panel 700 connects across exterior buoyancy tubes 300 for water deflection during forward motion of shuttle boat 100. Further, angle θ is associated with the topside 102 of boat 100, as opposed to the underside 104 of boat 100. Prow 400 is shaped as a natural keel as a result, as topside 102 begins to angle away from the water farther from prow 400, and underside 104 begins to angle away from the water closer to prow 400.

(20) FIG. 4 illustrates the same embodiment from the top, where the construction of inflatable shuttle boat 100 is more easily viewed. Seat tube 200 is in the middle, with a foot support tube 500 on either side of seat tube 200. Foot support tube 500 is smaller in diameter from seat tube 200 and exterior buoyancy tubes 300, and sits lower than the seat tube and the pair of exterior buoyancy tubes. The seat tube and the pair of exterior buoyancy tubes define a pair of elongate gaps therebetween so that users who are straddling the seat tube may place their legs on either side of the seat tube between the seat tube and the pair of exterior buoyancy tubes to comfortably place their feet onto the pair of foot tubes 500. Exterior buoyancy tubes 300 sit adjacent to foot tubes 500, and are typically larger in diameter to seat tube 200 for added buoyancy and stability. Prow 400 construction is also easier viewed in FIG. 4, and depicts how seat tube 200 and exterior buoyancy tubes 300 connect via panel 600 in an embodiment. Seat tube 200 is longer than exterior buoyancy tubes 300, and prow 400 is square-shaped, though this could be formed in other shapes in various embodiments, such as oval or circular. Panels 600 serve to further join the wider seat tube 200 to the exterior buoyancy tubes 300. Panels 600 act as safety covers by covering openings which could pose a safety hazard for human entrapment. Additionally, the numbers 1 through 6 in FIG. 4 illustrate where users may sit in boat 100.

(21) FIG. 5 illustrates the bottom of inflatable shuttle boat 100, with seat tube 200, foot tubes 500, exterior buoyancy tubes 300, prow 400, and an underside panel 700. Underside panels 700 are used as a water deflection shield to prevent water from getting between seat tube 200, foot tubes 500, and exterior buoyancy tubes 300 during forward shuttle movement across the water.

(22) FIG. 6 illustrates the back of boat 100, with seat tube 200, foot tubes 500, and exterior buoyancy tubes 300. This shows how each of the tubes connects and sits on the water. FIG. 7 illustrates the front underside of boat 100, with seat tube 200, foot tubes 500, exterior buoyancy tubes 300, prow 400, and underside panel 700 according to a further embodiment. Underside panel 700 may connect exterior buoyancy tubes 300 together, as opposed to connecting seat tube 200 and exterior buoyancy tubes 300 as depicted in FIG. 5.

(23) FIG. 8 illustrates how exterior buoyancy tubes 300 may interact with various motorized boats (the side profile of various motorized tow boats A, B, and C are each different). For different boats A, B, or C, the step distance and the step angle OA, B, or C varies. This illustrates how boat 100 and exterior buoyancy tubes 300 may successfully interact with various boats for loading of riders onto boat 100, with increased safety and stability by smaller step distances and step angles OA, B, or c. Embodiments of boat 100 thus allows for tight contact with motorized boats used for parasailing or other water sports, which in turn allows for safer transfer of riders from an inflatable shuttle to the motorized boat while both are in motion.

(24) To arrive at a tow boat, inflatable shuttle boat 100 may be connected to a motorized boat or Jet Ski by way of a towing rope connected to prow 400, and thus pulls inflatable shuttle boat 100 behind it while on the water. Users may sit on seat tube 200 as depicted in FIG. 14. In various embodiments, inflatable shuttle boat 100 may be shorter or longer, to accommodate different numbers of users.

(25) FIG. 9 depicts a perspective view of the shroud on the underside of the prow of the shuttle boat 100. The shroud extends across the foot tubes 500 and provides a water deflecting plane. FIG. 10 depicts a perspective view of the underside of the aft end of the shuttle 100. The aft end 10 of the seat tube 200 is rounded in this embodiment but other shapes could be used.

(26) FIG. 11 depicts a perspective view of the upper shroud area at the prow 400 of the shuttle 100. The shroud covers the area where the foot tubes 500 intersect the prow 400 section

(27) FIG. 12 depicts perspective view of the underside prow 400 and the sliding bridle system 12 and multiple tow points for the shuttle 100. Bridle system 12 includes a first series of tow points adjacent the prow of one exterior buoyancy tube 300 and a second series of tow points adjacent the prow of the opposite exterior buoyancy tube 300. A first rope has two ends connected to two tow points selected from the first series of tow points and a second rope has two ends connected to two tow points selected from the second series of tow points. Bridle system 12 further includes a pair of slides slidably arranged between the ends of the first and second ropes. The pair of slides are connected by a harness with a slideable tow ring configured to be connected to a tow rope. The sliding bridle system 12 is a unique solution to maintain a consistent tow force on attachment points while turning.

(28) FIG. 13 depicts a perspective view of passengers transferring from a parasailing boat 20 to an inflatable shuttle boat 100.

(29) FIG. 14 depicts a perspective view of a jet ski 30 towing an inflatable shuttle boat 100.

(30) FIG. 15 depicts a planar view of the underside of an inflatable shuttle boat 100 and features between its front end 50 and aft end 10. Seat tube 200, foot tubes 500 and exterior buoyancy tubes 300 may all be covered by abrasion guards 550 that prevent damage to the bottom of shuttle 100.
