Composite masts and mast-fuselage connection assemblies for hydrofoil sports boards

A hydrofoil assembly, comprising:

• a hydrofoil mast formed as an elongated member with a flared lower end;
• a fuselage formed as an elongated member with at least one planning blade attached at an end thereof, and comprising a mast attachment recess defined as a bore in the fuselage that is generally orthogonal to a long axis of the fuselage, where a bottom surface of the hydrofoil mast is coplanar with a bottom surface of the fuselage when secured in the mast attachment recess;
• and
• a securing assembly that secures the mast in the mast attachment recess in a first position and allows the mast to be removed from the mast attachment recess in a second position.

A mast-to-fuselage assembly for hydrofoil sports boards, comprising:

• a hydrofoil mast formed as an elongated member and including a securing structure;
• and;
• a fuselage configured for attachment at least one planning blade, wherein the fuselage comprises a mast attachment recess is disposed in the fuselage, and
• a securing assembly that is actuatable to releasably secure the hydrofoil mast to the fuselage by interacting with the securing structure, wherein the securing assembly includes a slidable locking member that extends to a first position to interact with the securing structure and secure the mast to the fuselage and retracts to a second position to allow the hydrofoil mast to be removed from the fuselage, the securing assembly further comprising an actuating member that moves the locking member into and away from the second position wherein the actuating member includes a pivot surface for rotation and a camming surface that interacts with the locking member and the actuating member is rotated.
