I have been looking for a thread on this topic but did not find one through the search engine on this site, hence this new thread. I have bought an Ocean Marine 40 Foot "classic" Trawler built in 1978. The boat is in very good condition. During this winter I store it dry inside a large and frost-free hall. Today I have been counting the valves that run through the hull. I counted 19, almost all in service for one or the other engine or accessory. However, some of them are completely unreachable if the engines are running or have just been running as operating them needs close contact with the exhaust at the rear end of one of my Ford Lehmans. My question is, what do my fellow trawler captains do when they leave the boat in the harbor? Close all the valves or leave them open?
