Winterizing Chespeake Bay

I have just purchased a boat in the deltaville area, and wanted to know if it is really necessary to winterize using antifrezze. I was thinking of dewinterizing the motor and just using some space heaters to keep the boat warm.

Maybe. It's a risk, though.

Up here closer to Annapolis, it would be even riskier. The temps certainly get cold enough to freeze the brackish water. The heater would probably save you -- unless the power goes out.

But if it's already winterized, why not wait until spring?

Not sure why you want to dewinterize the engine. Are you hoping to use it over the the winter? Don't like idea of leaving a space heater running unattended. Too many things can go wrong.

I'm with the others--a winterized engine just sits there doing what it's supposed to--not too many worries there. But space heaters running? High mischief potential. Losing power and having the cooling system freeze would be the nicer bad outcome. A wire heating up and shorting and burning down the boat would be the nasty one.

If you're considering using the boat over the winter, here's what we used to do when my family kept a boat in Norfolk. We winterized the head and fresh water, and ran antifreeze through the raw water intake on the engine. When we wanted to daysail, we'd leave the head and fresh water alone. We'd use the engine of course, but then redo the antifreeze on the engine upon return--only took a few minutes. The point being, we still winterized the engine even when we were using the boat occasionally over the winter. Just my two cents...
