I strongly suggest that you put in a propane detector--use the switchs and selnoids also. However I have seen several boats explode and burn which were not monitered--and have seen leaks found which prevented such diseasters. In a conventional monohull, the leak detector is at the lower part of the bilge and under the propane stove. Most likely in the PDQ, probably a single sensor under the stove will be sufficient. Not many bucks to pay for peace of mind and prevention of diseaster. Bob Austin
