I am new to this mail system. Not sure how to reply, or if reply should be directed individually or to all. I have red about the sponge idea. Also newer boats have something called a waterbox. Bascily I am trying to make my boat into a nice "old man's" boat. Maybe (going forward) a little less excitement generally, and a little more comfort. Just a little. I am an engineer(EE). I think I can do it, but I know I can mess it up. So I am taking time to ask around. No one in this area would do it for me for $100 or even $500. There is only one company that works on sailboats. I called them and two regular boat companies. I also just got a go ahead with the g-flex epoxy but still trying to get a call through to west systems. Jim Dahlquist
