ABSTRACT:
A folding boat is comprised of a bow section having a bottom, first and second side walls joined to the bottom and upstanding to respective first and second gunwales. The side walls terminate at a forward end forming a prow and the bottom and side walls are joined to a bow section bulkhead at an aft end and having a thwart connecting the side wall gunwales. A stem section has a bottom including a keel, first and second side walls joined to the bottom and upstanding to respective first and second gunwales. The side walls terminate at a stern end and the bottom and side walls join to a bulkhead at a forward end of the stern section and having a thwart connecting the side wall gunwales. A hinge extends across thwarts, permitting the stem section to be folded with respect to the bow section, whereby the respective gunwales are juxtaposed and which may be unfolded again to an extended configuration wherein the respective bow section and stern section gunwales and keels are contiguously aligned. An axle supporting a pair of wheels fastens to the bow section aft bulkhead with the boat in the folded configuration and a tow bar fastens to the prow, whereby the folded boat may be towed manually or with a vehicle. In preferred embodiments a transverse channel between the bow and stem section bulkheads retains a first beam and the stem gunwales retain a second beam capable of supporting parallel outriggers or parallel boats in a catamaran configuration.
