First Claim
Patent Images
1. A vessel direction control system for a small-scale vessel including a vessel body with a bow and a stern, the vessel direction control system comprising:
- a principal propelling outboard engine attached to a stern of a vessel body;
a subsidiary propelling outboard unit attached to a bow of the vessel body and including an electric motor for controlling a direction of the vessel body;
a bracket member fixed to the bow for attaching the outboard unit thereto in a vertically swingable and detachable manner;
a vessel direction detector for detecting the direction of the vessel body as a vessel direction;
a wind velocity detector for detecting a velocity of winds above the vessel body including a component representative of a direction of the winds;
a controller responsive in a first mode thereof, to a detected vessel direction to control the outboard unit so that the bow is oriented at a preset vessel direction, and in a second mode thereof, to a detected wind velocity to control the outboard unit so that the bow is oriented upstream the winds; and
a select switch for selecting one of the first and second modes of the controller.
