One embodiment of the invention provides a multihull watercraft having outermost hulls, a length, and a pair of propulsion units positioned inboard of its outermost hulls in a central ½ of the watercraft length. The propulsion units include propellers which are positioned to engage the water within the central ½ of the watercraft length and draft less than the outermost hulls. Because the outermost hulls provide protection from obstacles, the propulsion units can be operated propeller-end first, at a sufficiently high efficiency so that solar power for electric motors becomes an economically viable power source.
