Okapi, Thanks for the input, I have been looking at the Force10's and SigMar's for awhile now.
John, Thanks for the info. We'll be at the dock but also need a heater for full time cruising in cold environments. From a quick look on the web, the forced air heaters are going to draw 10+ amps and I think that's going to be a non-starter for us.
I'm looking into Sig Mar and Dickinson bulkhead and floor mount heaters now. I will definitely poke around other parts of the forums and see what I can find.
