30 years ago I had a Tiny Tot
stove - the usual forward bulkhead mounting - in a 35' sloop. It burned wood, coal or charcoal. It was very efficient, used very little
fuel and was clean when operating and dried out the interior quite well - including wet, cold New England winter sailing gear. Started the burning with newspaper just like a regular fireplace. Only during
lighting and in stiff wind would burned paper be drawn up the and out the Charley Noble onto the trunk cabin. We had to be careful when emptying the ashes not to spill (fairly normal concern with anything on a boat, I think) but we were quite happy with the heating. Further, given its small capacity, we didn't need much
fuel to heat the boat and storage of the
fuel supply wasn't a problem. Hope this helps, Roho.
