Hi All, I am planning on taking my trawler from the lower Chesapeake to Hilton Head this winter. I will be staying on board sometimes, but most of the time it will be vacant. I want to keep some sort of heat on to keep things dry. I was thinking of a couple electric space heaters, rather than my 2 zone cruise air units, while the boat is un-attended. Any thoughts on what type of heaters would be best for a 36' boat's cabin? I have a single 220 hp cummins equiped with a 120v engine block heater. A friend of mine, who is a retired coastie, told me to leave in plugged in, as this would keep condensation out of the engine and also heat the engine room area. Sounds like a good plan, but would there be any pitfalls to doing this? Any input is appreciated, as this is my first winter with the boat. Thanks
