The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator. Power transmission elements extend from the pedals down to a prime mover such as a propeller.

The present invention relates to an improved vehicle for use in water, in particular into the sea. More specifically, the invention relates to the structure of a vehicle of type called configured to have a hydrodynamic profile and to allow a user to turn with greater speed.

A user propelled flotation and transportation system, the system including first and second buoyant floats configured to be selectively attached and detached to a user's feet, each of the first and second floats including an elongate hull having a forward end and a rear end, a foot receiving portion provided on a top surface of the hull, a pair of fins extending downward along a length of the hull and arranged to be substantially parallel to form a channel along a bottom surface of the hull, and one or more flaps arranged between the fins and configured to pivot about a line between the fins that is proximate the bottom surface of the hull, wherein the one or more flaps are configured to be movable between a first position extending downwardly from the bottom surface of the hull, and a second position rotated back toward the rear end of the hull.

A paddle mount for a boat is described. The mount includes a generally t-shaped tubular body including a flange and a stem, where the length of the flange and the stem is adjustable and the ends of the flange are configured to rest on opposite sides of the boat cockpit. The mount is configured to couple to the front end of the cockpit and to an end of the stem, such that the t-shaped body may be rotated upwards away from the boat. A mount adapter is also described that may be used to attach a paddle to the boat using the mount.

An oscillating reversible motor providing a novel means of converting oscillating motion into selectable clockwise or counterclockwise rotary motion. More particularly, the invention presents a novel approach to a foot or hand pedal driven apparatus with which a traditional rotary water propeller or other output device may be employed in both forward and reverse directions of relative motion.
