A hydrofoil watercraft, in particular, a hydrofoil board is described herein. The hydrofoil board may comprise one or more of a body, a hydrofoil assembly, and/or other components. The body may have one or more of a deck surface configured to support a rider, a bottom surface opposite the deck surface, and/or other surfaces and/or features. The body may comprise a fore portion having a planing surface forming part of the bottom surface. The body may have an aft portion having an aft bottom surface forming part of the bottom surface. The fore portion may be toward a front end of the board. The aft portion may be toward a rear end of the board. An aft cross-sectional thickness between the deck surface and the aft bottom surface may be less than a fore cross-sectional thickness between the deck surface and the planing surface.

A water ski fin comprising a planar body and a plurality of chevrons. The planar body may have a top end, a convex leading edge, and a trailing edge. The mounting elements on the top end may mount the fin on a tail of a water ski. A bottom may connect the leading edge to the trailing edge. A plurality of chevrons may have alternating crests and troughs positioned in the trailing edge.

The present invention is a connector for an inflatable member. A portion of the connector extends within an internal volume of the inflatable member to define a recess for accepting a structural connection. The connector has an air-impermeable surface that is configured to maintain integrity of the inflatable member to allow the internal volume to be pressurized when the connector is bonded to an opening in a surface of the inflatable member. The connector can optionally pass through the opposing surface or otherwise engage the opposing surface to enhance its structural properties.

A hydrofoil board, system and kit with a mounting box system. The board, system and lit may include a board having a topside and an underside and a mounting box connected to the underside of the board. The mounting box may include a channel operable to slidably receive a securing device and operable to engage a mounting base, wherein when the securing device is operated, the mounting plate is secured to the mounting box.

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.
