They are actually making them for large boats now. Company not to far from reading is making them. Keeps the boat on yachts small cruise ships etc from rocking nearly at all. BUT!!!! These are quite large like the size of a 50 gallon drum or bigger. Its a thought but I cant see them not making any noise or being small enough. But I like where your head is at Competition shooters might like......they shouldnt care much about the noise.
