Abstract

A leisure boat is provided in a round form having a diameter of about 1 to 2 meters, and includes propeller means provided at a position closer to its bow from the center of the boat and the bow and having a mechanism for changing its driving direction and sensor means provided on the outside of the boat for sensing external force. The sensor means is so connected to the propeller means that when the boat comes in contact or collision with another boat, etc., the sensor means detects the resulting external force to transmit it to the propeller means, thereby changing its driving direction.

Claims

1. A leisure boat in a round form having a diameter of about 1 to 2 meters, comprising;

a motor casing disposed beneath the bottom of the boat and at a position offset from the center of the boat toward the front of the boat;

a steering wheel rotatabe throughout 360°

mounted on the boat and coupled to said motor casing through a steering shaft;

a reversible D.C. motor disposed in said motor casing;

propeller means coupled to said motor;

battery means offset from the center of the boat toward the rear of the boat;

a foot pedal positioned on the bottom of the boat;

a sensor means attached to the outside of the boat for sensing the application of external force applied to the boat; and

switch means including a manual switch, a reversible changeover switch, and a foot switch to selectively feed power from said battery through said foot switch and said reversible changeover switch to said motor,

said foot pedal being adapted to control said foot switch,

said sensor means being so connected through said manual switch to said reversible changeover switch such that when the boat comes in contact with or collides with another object, said sensor means detects the resulting external force and sends a signal to said reversible changeover switch, thereby changing the driving direction.
