I live up here on the Maine coast and ran a yard in the Boothbay Harbor area for 5-6 years. Wood hulls certainly do better in the water than out. We had an old Grand Alaskan that sat in her slip every winter - they covered the flybridge and cockpit areas against the snow - but nothing else.....Every spring we would haul that boat, clean the bottom and change out the zincs and lower her back in.......she did fine for as long as I was there for sure. As a side note, even hauling and storing inside a cold dirt floor building, planking on most wooden hulls opened up - some worse than others.
There are several marinas in this area that you could try - Hodgdon Marine - Boothbay Harbor and Southport Island.......Ocean Point Marina in East Boothbay.......Carosel Marine, again in BBH.......Several of these places leave some docks in over the winter where your boat could tie up.
Hope this helps some!
PS I'm a "newbie" as well......so far this Forum has been a great source of information and frankly some great humor to help get through the northern boatless season! Welcome aboard!
