Happy Clam is a 17′ x 5′ 6″ Seabright skiff. Among the inherent advantages of this hull form are its shallow draft, great stability, and low center of gravity. Full protection for the propeller is provided by the box keel. Flow of unbroken water to the propeller is made possible by tapering the keel to the propeller post. The relatively wide, flat keel maintains the boat in a level position when beached or trailerborne. The nearly level shaft angle, which is of value in performance, is not possible to achieve in any other hull form.
The skiff can be powered by an outboard motor up to 10 hp.
