I've got the same situation as treilley, and I have the same equipment running plus a desktop computer running 24/7. My bills have been $43/mo so far this winter. My electric meter just went nuts the other day and was recording me consuming 6000W (from my 30A connection, no less) so my bill for March is being disputed with the marina owners...
If your heat is reverse cycle provided through your AC unit, it will be the same power draw running the heat in the winter as it is the AC in the summer. That will cost a lot! And you can't use reverse cycle heat when the water temperature goes below about 42 degrees F, so you'd have to supplement with space heaters (REALLY expensive). I don't know if it gets that cold in NC, though.
