Best Space Heater for Boat

It's smaller than I thought, but sooooooo powerful. Powerful enough for any small space. Very easy and simple thermostat control. Of course this is very portable, because it's small size.

This has been an awesome heater. It actually works so good I have bought three for our boat, camper, and toy hauler.
They are great at circulating the air even when it's not putting out heat so it keeps the area warmer.
The one for the camper we used in Alaska and kept really warm.

I am with very happy with this purchase. I an inch of ice in my bilge and this heater had the ice melted within hours. And, despite the temperature being in the single digits for weeks now, no more ice has formed.

I purchased this as a primary heater for my 27' sailboat. I have already seen temps in the 20°s and my cabin was warm and cozy withouth excessive cycling. The thermostat is only accurate if the ambient temperature stays the same, if the temp falls, you do have to play with the thermostat to maintain an ideal temperature. But once set, it maintains the temperature on my boat within 2°-3°. I think that is impressive for such a small unit. It was also used on a friends 30' sailboat one night with similar results, though it ran for 10 minutes on a cycle on his boat vs 5 minutes on mine.
