Boston... freeze, thaw, freeze, thaw. You may have a cover, but moisture will get under it and into in the seems, in the threads maybe the weave. I might feel differently, if you were planning to use the boat occasionally, which would dry it out. Mildew would concern me as well.
But, they're your sails. Do with them as you please. You won't come back in the spring to find shreds. I'm only suggesting you will notably shorten their useful life.
Imagine what will happen if a winter storm manages to get your cover loose, even just one end.
