Where are you in MD? I'm down in Calvert County, we have a couple cats on the beach here, and there are more in Solomons. I have an older Hobie 14 (even older than that, its serial # is in the 4,000), and it was raced hard but has been upgraded and had a REALLY REALLY good bottom/paint job, with super stiff hulls (they sound like Waterrat 505 hulls, which are the best small boat hulls made). I still sail it hard (whats 30kts and 10ft waves...) but thats why I have a dolphin striker and trap wires

As for your deck delam issue, you can try the "drill and fill" method, but you might have to go to the porthole repair method.
