A vessel with a retractable thruster assembly, the vessel comprising a hull, a vertical thruster well within the hull, said thruster well having a bottom opening in a bottom plane of the hull. The vessel further comprises a retractable thruster assembly. This thruster assembly comprises: a thruster head with a propeller, a casing structure vertically guided in the thruster well, the casing structure having a lower end portion to which the thruster head is mounted so as to extend below the casing structure, the casing structure including a watertight compartment, an electric propeller drive motor being housed in said compartment. The thruster assembly is vertically displaceable between an operative extended position, in which the thruster head projects downward beyond the bottom plane of the hull, and a retracted position, in which the thruster assembly is raised and the thruster head is received with the thruster well. |
