ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of pedal propelled watercraft More particularly, the present invention relates to the field of bicycle accessories that enable the use of bicycle as a watercraft.
BACKGROUND
Boating is a popular activity for a substantial segment of our population. Various boating styles account for the many alternate forms of watercraft. One form is the common pedal powered watercraft In most previous designs of common pedal powered watercraft, the pedals are generally designed as an integral to the watercraft structure. Such designs are a common sight on small lakes and are generally used for recreational sightseeing or exercising.
Bicycling is also popular worldwide both for practical and recreational uses but is limited to land activity. If one wanted to both bike and boat, he or she would have to either opt for either a bicycle or a boat to do so. Accordingly, a pontoon watercraft that can accessorize a common bicycle for use on water would be useful for exercising or recreation.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a watercraft that can accessorize a common bicycle. More specifically, a watercraft that is attachably removable to a common bicycle, and that is propelled by the customary pedaling that ordinarily propels a bicycle on substantially solid surfaces, and that is steered in the same way that an ordinary bicycle is. It is a further object of this invention to provide a lightweight pontoon watercraft that provides minimal resistance to water and is difficult to capsize.
