This invention pertains to power for a boat, comprising a vertically mounted rotary sail device generally amidship of the boat, a power transmission driven by the sail device, pulley directed cable, connecting between the power transmission and a pair of opposed side oar devices normally disposed in the water. The sail device is constructed in a manner whereby it always rotates in the same direction regardless of the wind direction, creating a condition whereby the boat may be directed on a straight course toward any point of the compass. A second, lever operated cable and pulley is provided to control the oar devices in a manner so as to reverse the operation of the oars with a resulting reversal of direction of the boat. |
