How do you keep your shrink-wrapped boat dry?

I've used this product on my 21' ski boat when I put it away for the winter.

Couple of buckets strategically placed in boat before wrap?

I'm a BIG fan of Damp Rid also. Keep about 12 small containers in main hull and large tub in amas on my Searunner 31. In winter AND in general when boat maybe closed up on mooring. I seem to get by okay with some tarpaulins. I get very little mildew developing over winter. But I have the advantage of checking boat after storms, etc. So far so good.
