Abstract
A planing boat including: a hull having a boarding area; a screw unit having a screw, and configured to be rotatable with respect to the hull so that the expulsion direction of a water current by the screw can vary by 360 degrees; and a direction change mechanism having a turning drive force source, and configured to change the expulsion direction by rotating the screw unit with respect to the hull with a drive force of the turning drive force source.
Claims17
A planing boat comprising:
- a hull having a boarding area;
- a screw unit having a screw provided at the hull, and
- configured to change an expulsion direction of a water current
- a tilt sensor that detects a tilt of the hull with respect to a horizontal direction, wherein an expulsion direction of the screw unit is matched in parallel with a tilt direction of the hull detected by the tilt sensor.
