Watersport propulsion system for a marine watersport vessel

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.

         5 . The watersport propulsion system of  claim 2 , wherein one or more propellers of the drive unit in the forward-facing position protrude towards and/or beneath a hull of the marine watersport vessel. 
     
     
         6 . The watersport propulsion system of  claim 1 , wherein the drive unit is connected with a transom of the marine watersport vessel via a transom bracket. 
     
     
         7 . The watersport propulsion system of  claim 1 , wherein the drive unit comprises a first part and a second part, the first part being connected with the marine watersport vessel and the second part is rotatable arranged in relation to the first part. 
     
     
         8 . The watersport propulsion system of  claim 7 , wherein the second part comprises the one of more propellers. 
     
     
         9 . The watersport propulsion system of  claim 1 , wherein the drive unit comprises an electric motor. 
     
     
         10 . The watersport propulsion system of  claim 1 , wherein the drive unit comprises one or more sensor(s) configured to detect the rearward-facing position and/or the forward-facing position of the drive unit. 
     
     
         11 . The watersport propulsion system of  claim 10 , wherein the control unit is operatively connected with the sensor(s) so as to control that the drive unit is in the forward-facing position when the watersport propulsion system is set in the watersport mode of operation. 
     
     
         12 . The watersport propulsion system of  claim 9 , wherein the propellers are driven by the electrical motor, the electrical motor being configured to rotate in either clockwise direction and/or counterclockwise direction. 
     
     
         13 . The watersport propulsion system of  claim 1 , wherein the control unit is configured to control an angle of the second part of the drive unit and/or rotation speed, and/or rotation direction of the electric motor on basis of data received from the one or more sensor(s). 
     
     
         14 . The watersport propulsion system of  claim 1 , further comprising a system sensor, the system sensor being configured to detect if a person or obstacle is present around the drive unit. 
     
     
         15 . The watersport propulsion system of  claim 14 , wherein the system sensor is operatively connected with the control unit. 
     
     
         16 . The watersport propulsion system of  claim 15 , wherein the control unit is configured to move the drive unit into the forward-facing position if a person or obstacle is detected near the drive unit. 
     
     
         17 . The watersport propulsion system of  claim 1 , wherein the watersport mode of operation is activated by an operator of the marine watersport vessel, and/or automatically by the control unit. 
     
     
         18 . A marine watersport vessel comprising a watersport propulsion system of  claim 1 . 
     
     
         19 . A method of operating a watersport propulsion system of  claim 1 , comprising
 providing a watersport propulsion system, on a marine watersport vessel,   setting the watersport propulsion system in a watersport mode of operation,   arranging the drive unit in the forward-facing position F when setting the watersport mode of operation,   detecting that the drive unit is in the forward-facing position before activating the watersport propulsion system in the watersport mode of operation.   
     
     
         20 . The method of  claim 19 , wherein the drive unit is hindered for providing the propulsion if it is detected that the drive unit is not in the forward-facing position after the watersport mode of operation is activated.
