Go to a boatyard in the Area and get a quote for winter storage including hauling and painting the bottom (which they usually require you pay them to do now.) Don't forget about covering the boat. You will probably want to shrink wrap a boat that new. You could save 200 or 300 dollars doing it your self but it is 2-3 days of labor. Some boat yards make you unstep the mast as well.
On the south side of the sound you might be looking at 4000 worth of storage fees, before any repairs or up grade, maybe a little cheaper where you are.
