Do you have an egress window somewhere that you could slip the hulls into the basement?

I do not like letting boats sit outside, especially in the winter. The freeze\thaw process can't be good for things. Even if its butt butt cold, chances are the inside of the hull warms up just enough for the water to thaw when its in the sun. Then when the sun goes down, it just freezes again. Not a big deal if its dry, but its not. Unless you live in the desert its about impossible to get hulls completely dried out. My concern is water expands when it freezes, it gets into places, expands and slowly blows things apart.

I knock mine apart and hang it on the wall at the shop. I just made a couple of simple brackets out of 2x4's and set the beam sockets on them. The front and rear beam stack up in the triangle of the brace pretty well too.
