Same reason I cover it in the summer ... to keep it clean and dry. As a
matter of fact, I use the same cover summer and winter with a little extra
support in the winter to handle the snow load.

Interesting question - which leads to the question - why do we cover
our boats in the winter?

I've made up a reason - I don't want the deck to get wet and then go
through freeze thaw cycles that open cracks.

If I'm right, then if your cover keeps the boat dry, its doing what's
needed.
