I have a Westerly Chieftain (centre cockpit/rear cabin version of the Centaur) and I need to fit a gas locker. There are two fairly small/deep cockpit lockers which are really too small to have a gas locker and store sailing gear. Also if I put a gas vent to the starbord or port side I am fairly certain any proposed gas locker will fill with water. Has anyone faced this problem? Any ideas?
