From what I have seen here, the folks who kept their boats in "safe" dry
storage took a worse beating than those who simply tied them up well and let
them ride it out in the water.
I was in a small marina returning a lift motor cover I found adrift and all the
boats I saw were doing OK. There was a little cover and top damage from the
wind but they were all still floating.
I didn't linger to look too hard since this was one of the "closed" areas (Ft
Myers Beach) and I didn't want to be dodging bullets ;-)
If I was worried I would worry about bilge pumps failing since the shore power
was out. They would have a hard time keeping me from going in and charging my
batteries/moving the boat.
