Can I ask a silly question? Geez, don't tell any of the yacht
professionals hanging around the dock if you do this, but why can't we
simply install an ENGINE POWERED HEATER like the beast that turns my
stepvan into an oven into the boat's cooling water loop, like the water
heater??......Silly me.

That's a good suggestion in some situations - but the 2GM15 is a two
cylinder 15 HP engine commonly used on sailboats around 30 ft, and is
probably raw-water cooled, so your suggestion won't work.

Even if the engine has a fresh water cooling system, an engine-powered
heater like you suggest will only be useful while the engine is
running - unless the OP wants to leave his engine running all evening
while at anchor, it won't help.

I think the best solution for his heating problem is a small Espar or
Webasto diesel hot air furnace. He did mention that he has a Force 10
propane heater. The one I had one on a previous boat was a
bulkhead-mounted "fireplace" with no provision to circulate the air.
When I stood up in the boat, my head was cooking, but my feet were
freezing.... That sort of heater needs a fan mounted above it to
circulate the heated air.
