My thought was to pull heat off the engine much like the radiator
system in a car. The way the design is developing, there will be an
interior cabin of a sort or at least a place where one could get out
of the wind, rain, etc. Think of a Parker/Steiger type pilot house
without the adjoining cuddy space. This is where I would put the
heating unit.
========================================

Small commercial fishing boats have been using engine coolant heating
in the cabin for a long time. There are a lot of variables. For
example, the closed cooling side of a FWC engine will typically have
the highest available temperature (160 to 170 F), but a raw water
engine wouldl have a lower coolant temperature.

I didn't know that. When I was a kid, the lobsta guys used old French
made coal stoves in the cabins - they could keep the heat low and just
ticking over to keep the chill off.

One of my favorite memories was sitting off Baker's Island with one of
my high school buddies and his lobsta fishing father eating a fresh
made chowdah in the cabin of the lobsta boat.

My former Bertram 33 had a full flybridge enclosure (lots of
protection but somewhat drafty). We used to run in cold weather
using just a 1500 watt electric heater. It was comfortable in
temperatures down into the 30s. You could do something similar with a
lightweight Honda generator on the back deck. They are very quiet and
it would have other uses. I'd get a battery operated CO detector for
the cabin in any case.

That's a thought, but it's only 20 feet long - I'm trying to avoid
using a small generator, although I do have one.
