A paddle for stand-up paddle boards and other water craft includes a paddle blade at a lower end of the paddle shaft and a skeg/fin extending from the lower edge of the paddle blade. A method and system for transporting a user across water or other surfaces has a board or other water craft for the user to stand/sit upon and a paddle with the skeg/fin extending from the paddle blade.

The present invention provides a board mountable system for filming underwater video. The inventive board mountable system can be mounted to the underside of water vehicles for incorporating a camera for filming from an underwater perspective. The inventive board mountable system is shaped to minimize drag as a result of the mounted camera or camera system. Embodiments of the inventive system includes a fin shaped housing for holding a camera or camera system. In certain embodiments, the fin is removably attached to the water vehicle, such as a surf board, where the fin housing can be swapped with other fins being used with the water vehicle for controlling the direction of a watersports board in motion. These embodiments of the inventive system further include a connection means for connecting the fin to the underside of a water vessel.

This invention is directed toward a fin box capable of accepting either a Futures or an FCS fin without the need for any additional products being added to either the fins or the fin box. The box has an internally-adjustable wedge that can force the bottom of a fin into an indent, thereby giving it a cant or angle. The box also has channels for both FCS and Futures fins, such that a user can easily exchange either brand of fin without adding or subtracting items from the fins or fin boxes.

A clamp assembly for connecting a rudder to an aquatic device having a body with a first end, a second end, a top and a bottom. A clamp having a screw connected to a pivot pin disposed within a clamp head is removably connected to the top of the body for selectively applying a clamping force on the body. The clamp handle in some bodies tapering to an end to allow placement within a retaining slot of a fin box.

A universal, quick release foil mounting system is disclosed. The device is comprised of three mam parts: a first part being a mount plate that is fixedly connected to existing kite surfing, windsurfing and standup paddle boarding foils by means of fasteners; a second part being a base plate that is fixedly secured to the mast track of existing kite surfing, standup paddle hoarding (SUP) and windsurfing boardsalso affixed by means of fasteners; a third part being a quick disconnect system on said mount plate or base plate comprised of, but not limited to catch tabs, locking pins and slide locks etc. The mount plate is configured to receive the base plate and temporarily join the foil mast to the board. An object of the invention is to allow any foil having standard 165 mm90 mm (6.53.5) hole mounts (as well as other dimensions) to be quickly installed or removed from a board.

Disclosed is a foil arrangement in which a fuselage is connected to a mast without any tools. Further, foil arrangement is disclosed, for which end sections of the mast are inserted into receiving pockets of a mast batten, a shoe or a fuselage, wherein intermediate pieces can be provided on the upstream and/or downstream side.

The present invention relates to a resiliently flexible fin for a surfboard or another surface watercraft, the resiliently flexible fin comprising a titanium or titanium alloy core and an opening in the trailing edge that enables a portion of the rear of the fin to resiliently flex against the force of water as the surfboard is turned, which can generate additional forward thrust for the surfboard as the surfboard exits the turn and the fin returns to its unflexed state displacing water in its path with force.
