In one aspect, a wireless remote controller for a personal watercraft is provided that includes a watertight body and a rotatable thumbwheel disposed on an upper surface of the watertight body. The remote controller includes at least one magnet affixed to the thumbwheel such that the at least one magnet rotates with the thumbwheel. The remote controller includes a magnetic sensor configured to produce magnetic field data in at least two axes. The remote controller includes a processor operably coupled to the magnetic sensor and communication circuitry configured to communicate control signals to an associated personal watercraft. The processor is configured to determine an angular position of the thumbwheel based at least in part on the magnetic field data in each of the at least two axes and to generate a control signal based at least in part on the determined position of the thumbwheel.

An embodiment of a mast includes a first support configured for coupling to one of a foiling platform and a foiling assembly, and a second support configured for coupling to the other of the foiling platform and the foiling assembly and for coupling to the first support in a manner that allows adjustment of a combined height of the first and second supports. For example, such a mast can be configured to have first and second telescoping supports that can be extended and retracted to different heights so that surfers of different skill levels can use the same mast.

A floatable apparatus includes a floatable body defining a longitudinal axis parallel with the length of the floatable body, a supporting member positioned under the floatable body for exerting a lifting force onto the floatable apparatus and a coupling assembly coupling the floatable body to the supporting member. The coupling assembly includes a base adapted to secure to the floatable body and a joint adapted to secure to the supporting member. The joint is detachably attached to the base and movable from a first position at which the joint is pivotable about and detachable from the base and a second position at which the joint abuts and is secured to the base. A coupling assembly for a floatable apparatus with a floatable body under which a supporting member is positioned for exerting a lifting force onto the floatable apparatus is also provided.

A hydrofoiling watercraft is disclosed that includes a board having a top surface for supporting a user and a bottom surface. Extending from the top surface of the board is a handlebar. Extending from the bottom surface of the board is a hydrofoil including a strut and a hydrofoil wing. A propulsion system is attached to the hydrofoil.

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.
