ABSTRACT:
An acoustic buffer has a pair of inflatable cylinders that float in the water against the hull along the waterline around the bow of a boat to dampen noise of the water lapping against the hull when the boat is anchored. The cylinders are joined together by Velcro strips at the forward ends adjacent to the bow, and each cylinder extends toward the stern along the hull. The aft ends of the cylinders are tied to boat cleats in order to hold the cylinders snug against the hull. Each cylinder has a second inflatable internal cylinder. The inner cylinder is filled with water and the outer cylinder is filled with air by means of valves in the aft ends of the cylinders. The flotation levels of the cylinders may be adjusted by varying the amount of water in the internal cylinders. The buffer may be thereby adjusted to optimally dampen the noise from water lapping against the hull for various different hull designs and shapes. When the anchor is raised and the boat is prepared for traveling, the cylinders are deflated, detached, removed from the water and stored in the boat. Further versions of the invention include a unitary inflatable buffer structure that floats in the water around the bow and in contact with the hull along the waterline.
