3 years ago I reworked the interior of both my 5.2 hulls; in front of and behind the front cross beam. Delamination of the stringers is quite common in boats of that age. I reinforced all stringers and installed 3 bulkheads in each hull in front of the forward cross beam. In addition I installed bulkheads immediately infront of and behind the dagger board wells.The decks were easily removed, a lot easier than my P19 was. In the end I added about 6 lbs per hull.
