Re: Extreme Cold
We are in the water in the C&D canal, just off the Delaware Bay. We live aboard about half time.
Actually we have two steel sailboats, one is on the hard right now. We sail in Newfoundland and both boats have Espars and kero bulkhead heaters, with proper chimneys.
Our experience with Espar has been very good. The D4 has kept the boat quite nice down to lower single digits. But I close off the aft cabin during the day when real cold. On the worst night we also ran the kero bulkhead heater in the aft cabin, it got right toasty.
We still have condensation issues, frost on the ports, etc.
Boat was froze in hard.
But we were happy and cozy.
