I 'pologize for shouting, but this is important.

Putting a flowerpot over a stove heater is a recipe for carbon monoxide.
If you want to die, go ahead and do this for heat in your boat.

Let me second Gordon's suggestion. We live in NW Washington state, where
the winters are not bitter cold, but bloody chilly. A flower pot--make SURE
it is clay, and not plastic--about 6-8" in diameter will do an amazing job
of heating the cabin, with radiant heat that seems to permeate all over the
place. It is a very effective, very cheap sort of makeshift heater, but
should do the trick for you.

The problem here is that there is no way of guessing what the airflow
into the burner is going to be, or the exhaust... most flowerpots have a
small hole in the bottom which becomes the exhaust. A flowerpot over the
burner creates a partial recirculation of air within a combustion
chamber, with the result that it will *always* produce a higher
percentage of carbon monoxide than an open flame, and there is a high
risk that it will put out dangerous levels of CO.

Remember too, CO builds up in the body, you can suffocate from CO
poisoning in the presence of fresh air.

In short, using a flowerpot over a stove burner to heat the cabin is a
BAD IDEA!
