Abstract: A surface drive for a watercraft (100) that is operated in different operating ranges dependent on a speed of the watercraft (100). A trim angle (?) is adjusted automatically in at least one operating range, via a closed control loop, with detection of preset regulating parameters and is automatically controlled, in at least one other operating range, with detection of preset control parameters in a manner established for the operating range.

Abstract: A method of controlling a watercraft having a drive which can be pivoted about a control angle. A maximum adjustable control angle is automatically reduced by a defined gradient with an increasing speed. The drive is configured as a surface drive comprising at least two drive units, and the drive units are adjusted in the vertical direction about a trim angle (T) in a pre-adjustable automatic operating mode (301). During a driving mode in which the maximum speed is reached, once the control angle (?) exceeds a first threshold angle (?—41) which is smaller than the maximum adjustable control angle ?_L), the adjustment of trim angle (T) exits the automatic operating mode (301) and enters a stand-by operating mode (300) in which the trim angle (T) is manually adjusted until the control angle (?) falls below a second threshold control angle (?—42) and the automatic operating mode (301) is re-activated.

Abstract: A surface drive for a watercraft with at least two drive units that is operated in different speed-dependent driving modes. The trim angles (?—1, ?—2) of the drive units (140, 140) are adjusted automatically and independently of one another, in order to reach a defined rotational speed (n—40) at which the maximum speed (v—40) is reached, during the driving mode in which the maximum speed of the watercraft is reached.

Abstract: A method of controlling a watercraft having a drive which can be pivoted about a control angle. According to the method, a maximum adjustable control angle is automatically reduced by a defined gradient with an increasing speed. The drive is configured as a surface drive comprising at least two drive units, and the drive units are adjusted in the vertical direction about a trim angle in a pre-adjustable automatic operating mode (301). During a driving mode in which the maximum speed is reached, the adjustment of the trim angle (?), once it exceeds a first threshold control angle (?—41) which is smaller than the maximum adjustable control angle (?_L), exits the automatic operating mode (301) and switches to a stand-by operating mode (300) in which the trim angle (?) is manually adjusted until it falls below a second threshold control angle (?—42) and the automatic operating mode (301) is re-activated.
