ABSTRACT:
A manually powered boat for use as desired by one, two, three or more operators is disclosed. Balanced floatation is maintained regardless of the number of occupants/operators. The boat includes a buoyant hull, a centered, rotatable propulsion assembly enclosed in a housing, and a seat for at least three persons. Cranks for operating the propulsion assembly are included on each side of the housing. Foot pedals are arranged on the cranks to enable operation by a single operator/occupant while sitting in the center of the boat and straddling the housing. Alternately, two persons may sit on either side of the boat. For a three or more person operation, the pedals are positioned to allow adjacent legs and feet of persons seated side-by-side and immediately adjacent one another to be extended and moved in unison for comfort and coordination.
