I am thinking about leaving my boat in the water this winter rather than
hauling and storing on stands. The marina where I have a slip offers
this option and it includes electricity. Water is available at an outlet
that is left running all year. (keeps the water system clean)

My boat is in a protected section of the marina with floating docks and
finger piers. The marina staff installs bubblers on the pilings that
locate the end of the finger piers.

The marina stays open all winter with a management and mechanic staff.

Has anyone done this (in the cold winters of Cape Cod)? Any bad
experiences?
