I have been living aboard, mostly in BC, for most of the last 40 years, keeping warm with an airtight wood stove. I have got up to 14 hours burn time ,on a load. The beaches here are piled high with driftwood , free for the taking ( a very pleasant way to spend your time). 15 minutes work gives me a weeks worth of free fuel. Most non urban ,full time liveaboards here use wood stoves.
I lived without a chain saw until about 4 year s ago, no problem.
I improved my axe and splitting maul by running several passes of hard surfacing weld along the cutting edges ,and resharpening it, being careful not to grind all the weld off.
The important thing is to make sure your stove is airtight and big enough. Tiny fireboxes are a curse.
No matter how damp your boat gets, an hour and a half with the wood stove running, and it is dry as a popcorn fart in a sand storm( as long as your boat is properly insulated)
Several of my clients have told me their boat is the most comfortable home they have ever lived in.
If yours is not, it can be. You are doing something wrong.
