Benefits of technology

[0016] The hull further provides a pair of fullers integrally formed on hull and extending along each side of the hull from said keel to said stem to provide a greater wetting surface for the hull as kayak moves over a body of water. The hull also provides a pair of strakes for lifting the hull as the kayak increases speed over the water.

Problems solved by technology

Pedal-type watercraft have never been popular due the weight and maintenance of the gearing assembly.
Each sponson has a front wall that meets the water head on but becomes unstable as the water enters the keel at the tip of the boat causing a rocking motion.
Pedal-powered watercraft of the past also fail to present a hull design for traveling in rough water.

Embodiment Construction

[0041] The present invention is directed to an improvement over U.S. Pat. No. 6,210,242 which is hereby incorporated by reference.

[0042] With reference to FIGS. 1, a pedal-powered watercraft or kayak 10 according to the invention is illustrated. The watercraft 10 includes a hull 12, a pedal drive assembly 13, a deck 14, a keel 15, a stem 16 and a retractable rear rudder 17. The keel 15 is closed within the hull 12 to move within the water without allowing the water to pass through the watercraft from keel 15 to stern 16. Unlike the watercraft described in U.S. Pat. No. 6,210,242, the water is forced out of the way of the watercraft during travel. The hull further includes a central body portion 18 having a bottom surface 19 with a centrally formed concave recess 20 extending the length of the central body portion 18 between the keel 15 and the stem 16. The retractable rear rudder 17 is attached to the rear of the stem 16 and is used for guiding the watercraft 10.

Abstract

A pedal-powered kayak, the present invention offers a more rounded keel and stem which operates in the water leaving no or little wake in the front or the rear of the boat. Since little water passes into the boat there no rough ride. The hull further provides a pair of fullers integrally formed on hull and extending along each side of the hull from said keel to said stem to provide a greater wetting surface for the hull as kayak moves over a body of water. The hull also provides a pair of strakes for lifting the hull as the kayak increases speed over the water.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to watercraft, and more particularly to occupant-powered watercraft. [0003] 2. Description of the Related Art [0004] Pedal-type watercraft have never been popular due the weight and maintenance of the gearing assembly. However, in recent years, popularity has increased due at least in part to participants active in biking, swimming, canoeing and other types of water sports for individuals who are the health-conscious. With new recent legislation restricting the use of motorized watercraft such as jet skis due to safety concerns, water bike have increased in popularity. In addition, the pedal powered water vehicles have great advantages for use in hunting and fishing as they run silent and can be taken into rocky hazardous areas with the fear of damaging the motor. Pedal powered watercraft can travel greater distances faster than oar powered craft and can be quickly stabilized without dropping ...
