Abstract
Fast boats create a water resistance that has a detrimental effect on the consumption of fuel. The object of the present invention is to reduce the water resistance to a minimum by meansf of an arrangement that automatically adjusts the direction of the propulsion force and the trimming planes so that minimum water resistance is obtained.
Claims8
A water vessel (1) with stern propulsion (8), such as propeller drive or jet drive, and preferably provided with one or more movable trimming bodies (2 and 3), such as trimming plates,
- characterized in that, during operation of the water vessel (1), an arrangement strives to influence the same in such a way that minimum water resistance is obtained.
A water vessel as claimed in any one or more of the preceding claims,
- characterized in that each trimming body (2 and 3, respectively) is pivotable about the stern part (7).
A water vessel as claimed in any one or more of the preceding claims,
- characterized in that the stern propulsion (8) is pivotable about a central point in a downwardly-directed plane, such as a vertical plane.
A water vessel as claimed in any one or more of the preceding claims,
- characterized in that the central unit (6) adjusts the stern propulsion (8) and one or more trimming bodies (2 and 3) based on the position data so that minimum water resistance is obtained during operation.
