Abstract:

A small sailing watercraft designed to be operated primarily by a single rider standing on the deck and having an improved hull configuration for improved handling in all seas and all wind conditions. The hull is hollow and is formed with a generally narrow displacement hull with a substantially larger deck area closing it so as to accommodate various standing positions for the rider. A pair of sponsons are disposed adjustably at the opposite side of the main hull and are carried by outriggers that are connected to the main hull in an area where it is reinforced by internal bulkheads. The hollow hull also affords a storage compartment.
