...... all the time remembering that propane is heavier than air and settles in the bilge. Be careful.
We lived on our Crealock 37 sailboat, which had a propane heater and a range. We installed a sniffer in the bilge. That gave us peace-of-mind for the most part. The "sealed", gel Prevailer@ main batteries were located in the saloon under the seats, and that area adjoined the bilge. The funny thing was that when charging with our high-output Balmar alternator we would have to open a hatch in the cabin sole to let hydrogen escape or we would get a "false" on the sniffer. (??I suspect hydrogen since it is a product of charging, and whatever it was would apparently rise from the bilge ??) Makes one wonder if he could blow up his boat with a spark while charging....... 😱
