The idea of a wood stove sounds great to all the campers in us; BUT look at "WET" inspections; thers a reason that we have government "Saftey Authoriy" inspections, take heed and get something that has been designed for the application.
I started on the same wood burning tangent; but opted for a pricey propane marine heater that has the same flame effect as a wood burning stove without the saftey concerns of CO2; depleting oxygen etc fuel and weight problems of cast iron. I purchased a Dickinson Propane Stove on sale;( they also make wood burners but there very small and only burn small amounts of wood;) Ive used the newport for 2 seasons down to 16C below zero in a well insulated; home made double glazed CT at 3300 ft elevation and been overheated. Uses propane very efficiently. This is the one product that I have ever endorced; I cant speak more highly of the design and function; GREAT. Picture in my gallery. Theres others out there too designed for boats; I put tones of time into researching the saftey and asthetics and this "hits the nail squarly on the head, flush without a blemish....".
