Abstract

Abstract A knockdown, readily portable rider propelled water scooter or life raft includes two separate, readily attachable floats that can be manually attached together or disassembled without the use of tools. In assembly, the two floats are adjustably secured together in spaced longitudinal relation, to fit most adult size riders. The forward torso supporting float may also include a viewing window for the rider to look down into the water, and/or a compass for navigation when used as a life raft. A manually controllable rudder is journaled through the forward float, which may also be provided with grommets for supporting canopy poles and a canopy if desired, to shade the human torso. Elongate male and female rods extend from the floats for detachably securing them together by depressible buttons in the male rods and suitably spaced holes in the female rods. A crank shaft is journaled on the attaching rods, with foot cranks having foot receiving stirrups located between the attaching rods and synchronized paddle wheels secured on the outer ends of the crankshaft outside of the attaching rods. A hollow trunk space and trunk lid are provided in the rear float in which some of the knocked down parts may be stored when not in use, and in which personal articles or a survival kit may be carried when in use.
