I have a 1967 skifcraft all wooden boat.Really good shape for its age,I mean everything works and works good.Runs great and was well taken care of.The only problem I have is the fact that the trailer it is on is an older(original)holsclaw rollers down the center and smaller bunks near the rear.Very apparent that the 2x4 bunks in the rear/and the rollers down the center are not good support.It actually caused the rear off the boat hull to HOG..One side more than the other.Three feet in front off the transom and stops at the place the wooden 2x4 bunk stops..Wondering if re-bunking with 2x6 and more bow support and rear support will correct the hogging.I have been told may be able to let sit on the new correctly braced trailer with water in the hull??to speed up the process.Any info and or help would be greatly appreciated.I will try and get you guys pics....
