Hi, I have been offered the opportunity to purchase a Hobie 16 of unknown vintage (sail in the 12000's yellow and white panels) From a sail chart I imagine it will be a 70's model. My question is related to a problem with the port hull which has a pushed in appearance half way down the curve of the hull, starting just in front of the front pillar. This extends pretty much back to the rear pillar. From what I can see and feel the deck is quite sound as are the areas around all the pillars. However if I push on the hull side it flexes inward without too much pressure applied. Would it be better to steer clear of this particular hobie?...OR Is this a reasonably easy repair? Nick
