Abstract: A high efficiency aerodynamic sail system for boats comprises a triangular fabric sail pivotally suspended at its head from the apex of a tripod mast structure such that air impinging upon the luff of the sail is free from the turbulent wake of any upwind structure. The foot of the sail is attached only at its tack and clew ends to opposite ends of a spar which is pivotally attached at its center to a short stub mast centrally positioned in respect to the tripod mast. The sail luff and leech side deflections are caused to be identical by cables to provide a constant angle of attack of the sail to the wind along the entire sail height. A sail-shaping batten having a longitudinally varying cross section is employed along the foot of the sail. Loading of the batten by pressure generated by the wind causes the batten, and thus the sail, to assume an optimum airfoil shape.

The boat comprises a circular framework which is covered by a thin skin which seals the exposed surface of the boat. A circular opening at the top provides space for occupants. An engine and hydraulic pump are provided for generating a flow of sea water which is discharged from the pump through one or more of four pipes leading to the four openings.

Abstract: This invention relates to an outboard motor assembly and servo mechanism therefor, and particularly to one in which the motor, propeller drive shaft and propeller can quickly and easily be raised as a unit to locate the propeller at a position where the propeller will not cause cavitation at very slow speeds and where it will reduce the draft required for the boat on which the motor is mounted, but at the same time permits immediate lowering of the propeller to a position for high speed operation when deeper water is reached. The above is accomplished by providing an auxiliary transom adjacent the main transom which is mounted for limited reciprocal movement in substantially a vertical direction by a servo mechanism, preferably under the control of the operator of the boat. This enables the boat propulsion means to be quickly changed from a position for slow speed operation to a position for high speed and vice versa.
