Hello All,<br /><br />I have a 1972 Arrowglass tri-hull, which is getting a make-over. And like most older boat owners I noticed that the decking had some soft spots. So, I decided that I would replace it, well I found that the stringers were soft as well. Has anyone used the plastic decking material for stringer replacement. Its seems in theory that this would be the ideal material to avoid rot. Also I would like to inspect my transom, since I am this far, but I don't want to go cutting away the glass that it is inclosed in for no reason. Should I worry about the transom or not. I plan on using some 1/4"" aluminum for remouting the motor if for no other reason... piece of mind. <br />Thanks.
