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.

The invention relates to a device for adjusting the attachment points of a harness line (2) on a boom (1) for a sail-board or the like. It is in particular remarkable in that it includes a carriage (3) that is mounted sliding inside or outside the boom (1) or in an attached part. The harness line (2) passes through the passage orifices of the carriage (6a-6b) in order to form a loop (4), which allows the user to hang by his harness. The carriage (3) can be locked by an appropriate system. This device makes it possible to correct the position of the loop (4) easily during operation of the sail-board in the water by unlocking the carriage, sliding it and locking it in a new position. The length of the loop (4) can be adjusted by shortening or lengthening the harness line (2) with a clam cleat.

An inflatable object has a curved section, and an improved valve featuring a flexible chute that has an inner edge connected to said inflatable object and is rollable and unrollable between a rolled-up closed position and an unrolled open position. The inner edge is connected to said inflatable object along said curved section at a location and orientation operable to use pressure inside said inflatable object to resist unrolling of said flexible chute from the rolled-up closed position, thereby imparting a self-locking functionality to the valve.

The mechanical oar system is a manually powered propulsion system for a vessel. The vessel is a personal watercraft. The mechanical oar system is configured for use with a person. The mechanical oar system is powered by the person. The mechanical oar system comprises a plurality of drive mechanisms and a vessel. The plurality of drive mechanisms are integrated into the vessel. Each of the plurality of drive mechanisms is manually powered. Each of the plurality of drive mechanisms comprises a mechanism that moves an oar structure (referred to in this disclosure as a blade). The oar structure propels the vessel in a desired direction. Each of the plurality of drive mechanisms is oriented relative to the vessel such that the direction of the propulsive forces can be adjusted by the person.

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.

Some embodiments are directed to an analysis device for board sports, intended to be secured to a board, such as a surfboard or ski, at the interface with the user. The device includes: a force sensor designed to capture one or more forces generated by the user on the board; a position and motion sensor designed to capture the position, speed and acceleration of the board in space; and a processing unit or processor connected to the force sensor and to the position and motion sensor and designed to synchronize and process the data from the sensors.

The LED lights for a surfboard is a safety device. The LED lights for a surfboard is configured for use with a surfboard. The surfboard is a floating structure. The surfboard is a roughly disk shaped structure. The surfboard comprises a superior face and an inferior face. The LED lights for a surfboard illuminates when the LED lights for a surfboard is placed in water. The illumination of the LED lights for a surfboard discourages predators in the water from attacking the LED lights for a surfboard. The LED lights for a surfboard comprises a housing, an illumination circuit and the surfboard. The housing contains the illumination circuit. The housing mounts on the inferior face of the disk structure of the surfboard. The illumination circuit automatically illuminates when the LED lights for a surfboard is placed in water.
