Naramatac

Naramatac was a catamaran sailboat designed by Robert B. Harris in 1948 and launched in 1950. Its innovative use of asymmetric hulls later became a hallmark of the Hobie Cat.

Efficacy

Harris' design was not entirely successful, however. At speed the flat bottoms pounded, and it showed poor performance in low wind which he ascribed to deep hulls, lack of stability to carry additional sail, too much wetted surface, and too heavy construction.
