I know the season is ending.

What do you do with your boat(s) over the winter if you are not in the
southern climes?

I store my old classic in a shed. My newer boat spends the winter on the
hard in a nearby boatyard, in a cradle the previous owner had built for
her. The cradle has an A-frame that can be erected to support a couple
of tarps.

The old boat has a simple inboard marine engine that's easy enough to
service. The newer boat has a pair of diesels that i have an outside
contractor service. I take the batteries home.
