I am in the process of rebuilding a '94 FX1 that looks to have spent its whole life on the coast. The hull looks a little thin on the bottom from 14 years of beaching...it isn't soft anywhere (at least not soft enough to flex it with my hands) but when I put a flashlight up against the bottom and look inside the bilge I can see the light in a couple spots. Its the ski my G/F will be riding along with being my backup ski so it will not see heavy use, my question is should I worry about reinforcing it? Internal or external? Or just ignore it?
