So one small vent line to the top of the container ran up mounted on the outer side of the (gunwhale? the raised part of the cockpit where the sheet winches are?) then one out of the bottom to the stern to keep air circulating through to prevent any build up of explosive gases? Then place one propane sniffing sensor in the bottom of the cockpit storage then one in the bilge in the salon somewhere to be totally safe? I want it to be totally safe cause its my baby and will be my home this fall.
