I store my H16 outdoors in Utah using the same tarp option. I take my mast off the boat and hang it on the outside of the garage up near the eves and it stays dry and snow free most of the time. The boat gets the 10X16 tarp wrap and I use bungi cords that go from side to side under the boat. Last year I put a 2X4 accross the middle of the tramp from the front cross beam to the back and it shed the snow and water a little bit better. When we had snows of a foot or more I pushed the snow off with a push broom just so the weight wouldn't get to great. This is the 4th season and it has worked great so far. Don't expect the tarp to last much more than one season though. It takes the brunt of the sun damage so your boat doesn't.
