ABSTRACT:
TECHNICAL FIELD
The present invention relates to human propelled water craft such as kayaks and canoes and, more particularly, rotationally molded sit-on-top kayaks having open cockpits.
BACKGROUND OF THE INVENTION
Conventional kayaks comprise a hollow shell in which the kayaker's lower body and legs are received through an opening in the shell. These kayaks require a certain amount of skill to operate as the kayaker must learn to “self-rescue”, or roll the kayak into an upright position if the kayak is tipped over.
An alternative type of kayak has been developed and has gained increasing acceptance. This new type of kayak is referred to in the industry and herein as a sit-on-top kayak. As this name suggests, the user of a sit-on-top kayak sits in an open cockpit on top of the kayak hull. The sit-on-top kayak is somewhat similar to a surfboard in overall shape, but normally has a generally V-shaped hull portion and a deeper draft to allow better tracking. Modern sit-on-top kayaks are conventionally formed out of polyethylene using a rotational molding process to obtain a sealed, hollow shell. The process of manufacturing rotationally-molded polyethylene sit-on-top kayaks is generally discussed in U.S. Pat. No. 5,397,525 issued to the present Applicant.
The kayak discussed in the aforementioned '525 patent is a single seat kayak designed for use by one person. A seating surface, footwell, and spacing surface are formed in the cockpit of the kayak shown in the '525 patent. The Applicant is also aware of a number of two-person kayaks in which two seating surfaces and footwells are provide. The Applicant is aware of a three-person kayak where each person has a separate cockpit area; this kayak is very long and not practical for many people because of its length. A comfortable, stable three-person kayak has thus been difficult to manufacture because the overall length of the boat can be impractical.
The need thus exists for a sit-on-top kayak design that provides three seating surfaces and footwells associated therewith, but does not result in a boat that is inconveniently long.
From the foregoing, it should be clear that one primary object of the present invention is to provide an improved sit-on-top kayak design.
SUMMARY OF THE INVENTION
The present invention may be embodied as a sit-on-top kayak having a seating and footwell arrangement that allows three people to sit comfortably in a cockpit of a kayak. Inside the cockpit, three seating surfaces and footwells are formed. The footwells associated with the two rearmost seating surfaces are each divided into two footwell portions that straddle the two forward seating surfaces.
