Hey I have a 1976 Venture 22 and I have it on a roller trailer and the hull is flexing in about a quarter inch over a square foot area where the mid rollers sit. If you drew a line down from the rear of the windows down that is where the rollers are. Does anyone know how thick the hull is? If this is excessive or is the hull made to be flexible like this? The gel coat shows no signs of cracking, the screw driver test is good, and from the inside the resin and the glass look fine. I don't know anything about fiber glass and am not sure if it could be doing damage I cant see. Thanks !
