As described above in detail, the following effects can be obtained according to the ship steering assist device of the present invention. (1) When steering while traveling at low speed in a harbor, etc.,
Since the left and right fins descend from the hull and are located at the left and right sides of the rear edge of the rudder, the resistance of the fins causes
Compared to the case without the fins, the wake behind the propeller increases at the same ship speed, and the presence of the fins increases the flow of water passing between the fins and the rudder. The speed of the water flow along is maintained sufficiently, and the steering ability at the time of steering is improved. And
During cruising, by raising the fins above the water surface, an increase in resistance due to the fins can be eliminated. (2) If the fins that make a pair on the left and right are arranged in a C-shape that opens backward, when the fins are lowered and the steering is performed, the trailing edge of the rudder is almost continuous with the fins. Since it can be made to be in a state in which the control surface is increased, the same effect as when the control surface is increased by using the fin like a flap is obtained,
Even during low-speed navigation, a decrease in ship maneuvering performance is suppressed. (3) If the fins are provided so as to be continuously arranged with respect to the rudder when the rudder is in its descending state at the maximum rudder angle, the maximum fin angle is set when maneuvering at a low speed. This has the advantage that the turning moment of the hull is greatly increased.
