  • Single drive catamaran hull
    Patent number: 8109221
    Abstract: The catamaran hull includes a pair of substantially parallel separate hulls, connected by an intermediate hull portion, wherein only one of the separate hulls includes a propulsion assembly. Each hull is asymmetric, but differently configured, such that the off-center thrust created by the propulsion assembly in the one hull is substantially offset by the turning force created by the difference in the two asymmetric hull shapes.
