    摘要： The invention relates to a ship's propulsion and/or azimuth steering arrangement surrounded by water, said unit comprising an electric motor (5) in a chamber (4) formed by the unit walls, a propeller shaft (7) associated with the electric motor having a propeller (8) fitted outside the chamber (4). Arrangement includes means (12, 17) for pressurizing the chamber with air or some other pressurizing medium, the thermal conductivity of which increases with the pressurization. The invention also relates to a method for managing fluid flows in the propulsion and/or steering unit of the aforementioned kind, wherein the chamber (4) is sealed (10, 16, 26) on the one hand against the water pressure from outside and on the other hand, correspondingly, against other compartments (11, 15) of the ship. The chamber (4) is pressurized by means of a flowing medium, and monitoring of the pressure in the chamber (4) is performed, and the composition of the medium escaping from the chamber (4) in a controlled manner is monitored (20). Further,the invention comprises a method for improving the cooling by means of a pressurized gaseous medium.

    摘要： A marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12), where said propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the gearbox (10) and where a transition cone (18) is located between the gearbox (10) and the propeller hub (14). The transition cone (18) has: - a front end (20) located in connection with the gearbox (10), where said front end (20) has an initial peripheral cross-section dimension (C) essentially corresponding to the main peripheral cross-section dimension (B) of the gearbox (10); - a rear end (22) located in connection with the propeller hub (14), where said rear end (22) has a connecting peripheral cross-section dimension (D) essentially corresponding to the main peripheral cross-section dimension (A) of the propeller hub (14). The invention is distinguished in particular by the fact that the transition cone (18) includes a bulb-shaped shoulder part (24) located between said front end (20) and rear end (22), the largest peripheral cross-section dimension (E) of which exceeds the initial peripheral cross-section dimension (C) of the transition cone (18).

    摘要： The present invention is concerned with a hull assembly for an aquatic vessel, and particularly with a catamaran vessel provided with the hull assembly. The hull assembly has a plurality of flexible modular containers units. Each of the container units is connected together to form an outer shell structure with an inner hollow section. Each of the container units has an opening facing the inner hollow section. A plurality of inflatable bags are housed within each container unit. Each of the inflatable bags has an inlet for injecting a gas into each of the inflatable bags so as to provide rigidity to each of the container units. The hull also has an inner keel connecting the hull sections together within the inner hollow section along a longitudinal axis of the hull. The inner keel is provided with openings in registration with each opening of the container unit. An outer skin coat covers the container units and the inner keel.
