Abstract: A watersport propulsion system for a marine watersport vessel includes a drive unit arranged rotatable from a rearward-facing position to a forward-facing position, and vice versa, a control unit being operatively connected with the drive unit. The control unit is configurable in a nominal mode of operation and in a watersport mode of operation. The control unit is configured to operate the drive unit in the forward-facing position when in the watersport mode of operation and in the rearward-facing position otherwise.

Abstract: A method for performing a sideway displacement of a marine vessel. The marine vessel includes a first and a second propulsion unit, a first and a second rudder respectively associated with the first and the second propulsion units, and a bow thruster. The first and the second propulsion units, the first and the second rudders and the bow thruster are operable via a single driver interface. The method includes the steps of; via the single driver interface operate the first and the second propulsion units and the bow thruster so as to provide a total thrust and set the rudder angles of the first and the second rudders, to thereby steer the displacement of the marine vessel during the sideway displacement.

Abstract: The present invention relates to a method for performing a sideway displacement of a marine vessel (10). The marine vessel (10) comprises a first and a second propulsion unit (26, 27), a first and a second rudder (31, 32) respectively associated with the first and the second propulsion units (26, 27), and a bow thruster (37). The first and the second propulsion units (26, 27), the first and the second rudders (31, 32) and the bow thruster (37) are operable via a single driver interface (22). The method comprises the steps of; via the single driver interface (22) operate the first and the second propulsion units (26, 27) and the bow thruster (37) so as to provide a total thrust and set the rudder angles (?1, ?2) of the first and the second rudders (31, 32), to thereby steer the displacement of the marine vessel (10) during the sideway displacement. The present invention also relates to a marine vessel single driver interface steering arrangement which can be calibrated using the disclosed method.
