The disclosure includes systems, assemblies, sub-assemblies and methods for securely attaching components of a hydrofoil for use in water sports. The hydrofoil may include a mast assembly and one or more wings. At least some components of the hydrofoil may be assembled using toolless connections. The toolless connections may prevent relative axial and/or radial movement between components of the hydrofoil.

The disclosure includes systems, assemblies, sub-assemblies and methods for removably and securely attaching a hydrofoil to a board used in water sports. At least some of the systems include toolless removable attachment. In various embodiments, the attachment a hydrofoil adaptor mechanically attached to a trench frame by one or more toolless locking assemblies.

A motorized surfboard fin attached to the bottom of a surfboard to assist a surf rider in paddling, propulsion, and catching a wave, is disclosed. The motorized fin device integrates a propeller, motor, battery, charging assembly, and related electronics, which are activated by the rider via a remote control. The fin is adapted to fit standardized fin securement systems by way of interchangeable connectors. The remote control has geolocation tracking and wireless charging capability. A software application for use with a smartphone is used to perform configuration and maintenance functions.

A watercraft manoeuvring device for mounting on a watercraft is disclosed comprising an elongate member having a mounting end and an opposed fin end that is spaced from the mounting end. The device includes a mounting formation on the mounting end for mounting on the watercraft and a fin mounted on the fin end. The fin has a bearing surface for interacting with water and the elongate member is capable of flexing when the fin is subjected to hydrodynamic water forces when travelling through water. The device may be integrally formed from a polymeric material. A watercraft such as a surfboard having the watercraft manoeuvring device is also disclosed.

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.
