The invention relates to a watercraft having improved characteristics for travel in ice, particularly an icebreaker, supply vessel, cargo vessel or corresponding, which watercraft has a hull, which has at the stem portion a propulsion and steering arrangement, which is mainly responsible for movement and steering of the watercraft and which includes at least one skeg-like projection, in which is located at least one propeller device. In accordance with the invention, said skeg-like projections comprise two units located on different sides of the centre line of the hull. Said propeller device is located at the stem end of the skeg-like projection. In addition, the skeg-like projection has between the propeller device and the hull of the watercraft, in the longitudinal direction on the skeg-like projection, one or more thruster devices to provide a water flow mainly transverse in relation to the hull.

Methods and systems are for controlling movement of at least one propulsion unit on a marine vessel. The method comprises plotting a first plurality of points representing a first surface of a first propulsion unit and plotting a second plurality of points representing a second surface. The method further comprises limiting movement of at least the first propulsion unit such that the first surface does not come within a predetermined distance of the second surface during said movement.

In a hybrid type marine propulsion device including a main engine and a motor, low fuel consumption is realized by a compact configuration and highly efficient drive control.A marine propulsion device includes a clutch 7 provided on an input shaft 6 of a main engine, a horizontal input/output shaft 8 connected to the clutch, a vertical shaft 11 connected to the input/output shaft through an upper bevel gear 9, a horizontal propeller shaft 13 connected to a lower end of the vertical shaft through a lower bevel gear 12, and a propeller 14 at the other end side of the propeller shaft, in which the propeller is revolved around the vertical shaft to set a propulsion direction, wherein a motor generator 20 is mounted on a floor 3, and connected directly to the other end side of the input/output shaft. In a low rotation region, motor propulsion is performed, and in a high rotation region, hybrid propulsion in which the main engine is assisted by the motor is performed.
摘要:
A propeller drive for boats features a transition cone between the gearbox housing and the propeller hub(s). The propeller hub (that is closest to the gearbox housing) is smaller in cross-sectional dimension than the gearbox housing. The dimension of the front end of the transition cone corresponds to the cross-sectional dimension of the gearbox housing, and the dimension of the rear end of the transition cone corresponds to the cross-section dimension of the (closest) propeller hub. The transition cone has a bulging shoulder between the front and rear ends, the largest peripheral cross-sectional dimension of which is greater than the cross-sectional dimension of the front of the transition cone.
