Don't ALL boats have moisture issues? I use a Damp Rid basket, empty the bowl and refill the basket every time I visit the boat (~ 1-2 times a week, if I'm lucky). The catalytic heater will add to the moisture, but it's still the only practical, safe way to heat the cabin without being on shore power.
Peter, a typical CO detector will NOT detect propane, at any level!!!
They detect Carbon Monoxide, which is a by-product of the incomplete combustion of the fuel
, and not a component of the fuel
itself. You would need a combination sensor which detects both CO and explosive gasses. They used to be fairly expensive, but now you can pick one up for <$50.
Also, a CO detector will probably not prevent death by anoxia due to the combustion using up the oxiygen in the space being heated. Keep that companionway hatch
