Just out hauled my boat after nearly two years in the Med, of which last nine months it hasn't moved due to working overseas. It is copper coated, and also have Jaycar USAF fitted over the stern gear. I am pleased with results - particularly the stern gear. There were a few barnacles near the waterline, but most of the hull was just covered in a thin layer of mud which could be wiped off with a sponge. Five minutes with a pressure washer was all it too to prepare the boat to go back into the water.
