Re: Why doesn't anyone use propane refrigeration on a boat?
Probably for the same reason that ammonia gas refrigeration is avoided ... if you get a leak you get "!!!!". Propane gas in an RV if it leaks simply 'drains' to the tarmac; in a boat it 'drains' to the bilge. Propane 'sniffer alarms' arent 'foolproof'.
Its all a 'safety issue'.
