Abstract
A method of steering a planning V-bottomed boat with double individually steerable outboard drive units with underwater housings (), which extend down from the bottom () of the boat. When running at planning speed straight ahead, the underwater housings are set with 'toe-in', i.e. inclined towards each other with opposite angles (alpha) of equal magnitude relative to the boat centre line (b). When turning, the inner drive unit is set with a greater steering angle than the outer drive unit.
