Here's my setup. Its probably not legal or safe or up to code or anything.
but so far, it has worked. I had 30A power, 125V. I got an extension cord,
bobbitted it (cut off the male end, heh heh), and put on a marine 30A
connector. I run it to a Y-cable, running to a west marine 'air dryer' (i.e.
small heating element in a protective chassis) beneath the cabin ladder and
to a cheap Target clip-on fan clipped to the edge of the chain locker door
pointing up through the vent above it.

The combination of a heater and forced ventilation does a much better job at
keeping the condensation at bay than either appliance alone, and I have
tried each alone extensively.

> 1. It has to be SAFE

My setup probably wouldn't pass inspection. It would probably be better if I
put a 15A fuse in there somewhere.

> 2. It has to be CHEAP

My setup IS cheap.

> 3. I would rather not drill holes in my boat

I run the cord out the forward hatch, up to some velcro on the bow pulpit,
and looped down to the shorepower, in such a way that any drips on the line
drip into the lake, not into the socket.
