Title: Vessel
Inventor: ARAI YUJI
IPC: B63B1/40
Filed: 2022-04-04
Abstract: To provide a vessel capable of improving propulsion efficiency during sailing, and a control device.SOLUTION: A first buoyance body 3A and a second buoyancy body 3B are larger in under-water resistance as it goes upward from a vessel bottom. Thus, in the first buoyancy body 3A on the right side in which a main hull 2 inclines, a portion with large upper resistance is also disposed under water. On the other hand, in the second buoyancy body 3B on the left side, a portion with large upper resistance appears out of a water level. Thus, as shown in Fig.3(b), resistance RF2 of the second buoyancy body 3B on the left side becomes smaller while resistance RF1 of the first buoyancy body 3A on the right side becomes larger. Such a resistance difference can cancel turning-round moment MT of turning left caused by right inclination of the main hull 2. Thus, the turning caused by the turning-round moment MT can be dealt with without operating a rudder 15 which reduces propulsion efficiency.SELECTED DRAWING: Figure 3
