  • Foil arrangement for a planning craft
    Patent number: 4665853
    Abstract: A catamaran including two hulls defining a tunnel between them. The tunnel is bridged below the waterline by transversely arranged hydrofoils. The relatively larger mainfoil is located behind, and the smaller trimfoil in front of, the longitudinal center of gravity of the catamaran. This arrangement considerably reduces the high hump resistance of the catamaran.
