摘要： PROBLEM TO BE SOLVED: To solve a problem that a breakwater effect is insufficient because a buoy floating and moored on a race water surface in a motorboat race station, a river, a reservoir, a lake, and sea and having a breakwater function cannot be maintained in a straight line on a water surface.
SOLUTION: In this buoy composed of pultiple netlike inner cylinders incorporated in a netlike outer cylinder and having the breakwater function, clamping bolts are fitted into both ends of a hollow pipe provided at the center of the netlike inner cylinder and the clamping bolt and a wire rope having stoppers at required intervals pass through the hollow pipe to fix the buoy by positioning the stoppers at front and rear ends of a semicircular cap of the buoy. A chain of an anchor connected with an eye bolt of a cylindrical clamping body fitted around the buoy through a shackle is crossed and is fixed on the sea bottom to handle the upper end of the chain on the water surface.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a race boat strongly collides with a wave suppressor having a guard rail, a player thrown away from the race boat collides with a steel member or a pole of the wave suppressor passing over the guard rail, is wounded or killed in the worst case recently because the revolving speed is substantially increased by the progress of driving technique such as monkey turn and the improvement of the propeller in the water surface of a speed boat race course.
SOLUTION: In a net type safety device, a plurality of posts is erected on the wave suppressor, A wire rope or others is stretched between the posts at the height of 1 to 2 m from the upper end of the guard rail, a protecting net is suspended from the wire rope or others, the lower end portion of the preventing net is secured to the upper portion of the guard rail.
