I inspected the Oyster 82 to comply with USCG regulations. We were deficient in two ways. One the oil discharge plaque which has to be in the engine space – cheap and easy to rectify. The other is the need for a 12 inch (thats correct!!) diameter ships bell. The bell is sized according to the vessel. It is now stored and will never be used and takes up tons of space but if I get pulled over during the AC events I will be good to go!
