Commander Pete,

If you decide to replace only the pressboard that was under your tracks, then here is a nice solution. The product called Starboard is wonderful to work with. I replaced my original mainsheet traveler with a nice piece of (flat) stainless track from another boat. I used Starboard to put underneath it. By choosing the proper thickness and placing it between and outside (but not over) the original elevated mouting points, I did not have to modify the fiberglass in any way. One works with Starboard just like wood and it comes in various thicknesses. That is how I planned to install the jib tracks until this thread convinced me to put at least 4' tracks on and the stainless I have is only 30 inches.
