摘要:
A fin for use on a surfboard or another watercraft comprising a fin section that can be releasably coupled to the base of the fin, and the fin section can be slidably adjusted relative to the base in a direction towards the leading edge or the trailing edge of the fin. Following adjustment, the position of the fin section can be secured to the base with one or more locking means.
摘要:
A fin plug (10) for a water craft, said fin plug (10) including: a top surface (15) and a bottom surface (20); at least one fin cavity (25), for receiving a base element of a fin, extending inwardly from at least one opening in the top surface (15); and at least one hole (35) or recess in the top surface (15) adapted to be filled with foam.

The invention concerns a remote control device for controlling a towing vessel, for example during water skiing. The remote control device comprises a control unit (10) adapted to be connected to a towing vessel (70) by a cable (15). The control unit (10) is adapted to control a power source associated with the towing vessel (70) to permit the vessel (70) to travel at a desired speed and to convey helm instructions to the towing vessel (70). A Hall-effect sensor (52) associated with the control unit (10) enables control of speed or the conveyance of helm instructions. Optionally, one Hall-effect sensor (52) enables control of speed and a second Hall-effect sensor enables conveyance of helm instructions.

A wave generating apparatus mobile application controller and method is provided in which a mobile controller actuates a plurality of wave generating chambers in sequence using a delay between actuation of each chamber to produce a rideable wave in a pool. The mobile application controller allows the user to select the exact type of wave to be produced by the wave generator apparatus by selecting size, shape, and pattern of the wave. The application also allows the user to use a camera to photograph or record herself or someone else, even while riding a wave.

This invention involves a pair of shoe boards-floats (1) which, with the assistance of a pair of propelling sticks, allow a person to move at an upright position standing on them on the sea surface using solely his muscular power as energy. The reason the shoe boards (1) acquire a point of reference and allow the exercising person to move forward by sliding is the properly adjusted different shape between the prow (2) which shows small resistance compared to the stern (3) or the alternative shapes of the stern (3a) and (3b) born by two of the shoe boards and the blade (10) which is hydrodynamically auto-activated and operates as a mechanical system for the restraining of the regression of the board.
摘要:
A release arrangement for a sailboard footstrap which has a female member (22) and a male member (74). The female member (22) is composed of two identical components (38, 40) which locate together by means of pins (152) locating in apertures Chamfered apertures (48, 148) in resilient arm portions of the female member (22) are adapted to receive and retain frusto-conical bosses (94, 90) on the male member (74). The bosses (94, 90) are located on a portion of the male member (74), the sides of which abut pins (152) when relative rotation of the members (22, 74) about the engaged bosses and apertures (94, 48; 90, 148) occurs, the abutment serving to lever the bosses (94, 90) from the apertures (48,148) at a predetermined magnitude of force exerted to cause rotation. The male (74) and female (22) members may also disengage at other predetermined mag- n i tudes of forces exerted upon the arrangement in other directions.
