Yes, I know the dangers of weather exposure with plywood. It is well sealed with spar varnish and we only use it on weekends when we are actually on the boat. I expect it to last a very long time considering how few hours it is exposed.
Tried the towel approach and didn't like it. The doors work great.
Yes guys, I get your hint that it doesn't look so hot but it works for me and the wife is happy - not just happy, but extremely happy. As long as she is happy, life is good.
