I haul out every other year in Rhode Island
For 15 years I have left my boat in the water every other year. Until 3 years ago I had a Morgan 30, now a Hunter 40.5.Ice is not an issue with me because of the tide range and the proximity to open water. We might get a slushy surface or some light skim ice but that's all.Be sure to check your rigging each year. This may mean taking a ride in a chair up the mast to check the shroud ends. I believe that the rigging, mast, and all take more of a beating with all the extra handling when taken up and down than just leaving it up.There is a LOT LESS work to decommission an recommission when the boat is in the water. You might want to short haul to wax your topsides and change your zinc.Be sure that someone checks your boat at least once per week and preferably every day or two. Use double docklines and chafe gear, and be sure that your boat is tied in such a way that it cannot touch anything. Winter-long use of fenders is NOT acceptable. They will leave marks that cannot be polished out. Be sure every thru-hull is closed and that the stuffing box is not leaking. Pump antifreeze into the inside of the seacocks and be sure to eliminate every pocket of water that can freeze. Pay particular attention to water trapped on top of closed seacocks.Winterize everything just as if you were hauling out.Have a nice winter.Rich
