Two options in my book... blue tarp it from home depot or use the boat!
I tarped my boat every year but last year. She only sat for 8 weeks without use though in Jan and Feb. Tarping or shrink wrapping prevents water from getting into small places and expanding when freezing. Or moisture sitting in areas that seals may have been compromised for a while. For example if snow sits on a boat for a while and melts over a week or so and your deck plates are leaking, you will have had water getting into the wood of the deck not giving a good chance to dry out.
If you dont plan on using it, tarp the boat. If you do, make sure you have good seals and keep the bow up so everything drains off as quickly as possible.
(Not sure I would recommend shrikwrapping as I understand that it keeps condensation and moisture trapped under the wrap not allowing the boat to breathe or dry out - tarps tend to allow ventilation)
Just my opinions.
