We went sailing Saturday and it was worth the effort to consider extending the season. At what point does saltwater freeze? I can flush and preserve the potable water system with RV antifreeze. The portipotti can be removed when not on the boat. The bilges remain dry. That leaves me with the heat-pump and engine cooling.
The heat-pump saltwater cooling system could be purged with low pressure air. It would be nice to have for camp-outs. I'm reading a book on sailboat diesel engines now.
The thing we noticed this weekend is how chilly it was on the water. Blue jeans won't cut it.
