Abstract: In an apparatus for controlling posture of a small boat having a hull and an even number of outboard motors mounted side by side on a stern of the hull, each equipped with a propeller driven by an engine and a throttle actuator adjusting a throttle valve opening of the engine, an inclinometer is installed in one of the outboard motors that produces an output indicating inclination of the hull relative to a vertical axis around a roll axis. It is determined whether the hull inclines to port or starboard from the output of the inclinometer and when it does, operation of the throttle actuators of the outboard motors are controlled on a side determined to incline downward to increase engine speed, while controlling operation of the throttle actuator of the outboard motor on a side determined to incline upward to decrease the engine speed.

Abstract: In an apparatus installed on a boat (A) in plural boats including (A, B) for avoiding collision with the boat (B), there are equipped with first and second radio-wave transceiver units installed at spaced positions that transmit to and receive radio waves of a predetermined frequency from the boat (B), and first and distance calculating units that calculate clearance distances from the boat (B) based on attenuation degree of the radio waves transmitted from the boat (B). An intersection point of circles whose origins in an x-y coordinate plane are set to positions corresponding to the first and second positions and whose radii are set to values corresponding to the calculated clearance distances. Direction and position of the boat (B) are estimated from the intersection point, and an instruction necessary for avoiding collision with the boat (B) is issued based on the estimated direction and position.
