Bill, that is not my boat house, Here is a picture of mine. My stern faces west/southwest and I live in Houston, my concern is the uninhabital heat of the summers down here. I've been told by the locals to keep wax on the boat with UV inhibitors and that really helps. I can "suck" my boat up into the roof wiht the tower up ( the roof is pitched) but not enough to keep it out of the sun all the time. the afternoon sun is what I'm worried about. I've heard good things abotu sharkskin material, it's usually one below sunbrella.
