Me Too
I am currently using a 15' x 30' tarp. This is my 5th winter of this type of storage and I have gone through 4 tarps. Lost a brand new one early this winter when we where hit with 100mph plus winds. Any cover that I purchase would have to be pretty beefy. The lack of pooling is also important to me. I use pvc pipe bent over the mast and tied to the lifelines and stachions for support. Prior to this winter, I have always had to knock snow and pooling water off of the tarp, especially near the bow. This year I raised the front of the mast up about a foot above the normal attachment at bow rail (used a wooden human type crutch for a mast crutch). The mast is now horizontal to the deck, and has pretty much eliminated the pooling problem.
