摘要:
The present invention relates to a marine vessel (1) with a hull (10) with a bottom (11), a bow, a stern (13), and a propulsion arrangement (2) including at least three propulsion units arranged at the stern of the marine vessel. The marine vessel (1) has a base line and a centerline. The at least three propulsion units include a centerline shaft propulsion unit (21) with a shaft line (22) and a propeller (23) and two turnable propulsion units (30) with respective propellers (31) and arranged at opposite sides of the centerline shaft propulsion unit. For improving thrust efficiency, while maintaining optimal steering capability, the propeller (23) of the centerline shaft propulsion unit (21) is arranged at a given distance aft of the stern (13) of the marine vessel (1).
