Chaos Theory has two 40ST’s on the cabin top with cam cleats on the vertical surface behind them. We always run the #1 Genoa to the leeward side winch. We have turning blocks aft of cabin top tracks to cross sheet the #3 to the windward winch so during a jib/Genoa change, the new sail can be sheeted before releasing the old. If a halyard needs tensioning, the top half of either winch can be used with the self tailer ( not ofter necessary).
