I sold my runabout many years ago, and I don't keep my boat stored on a
trailer, it says in the water unless I have it hauled for maintenance.

I would like to do that, but you would be very surprised at what our water
does to stuff left in it over the winter.
I left a 400 pound sailboat in a large hoist. Come Spring it was 30' away,
turned 180 degrees (at least; maybe 900, who knows) and one hoist leg was
bent. I was happy the boat was out of the water.
My neighbors run pumps under their docks all winter so they don't get ripped
out; but I don't have electricity. I have had some boards ripped off it,
but thankfully the dock has held up.
