I have a 1976 Pearson 365 Ketch that my family and I have cruised to the Bahamas and back and I loved the stability and strength however it is becoming too small for my family of 5. We are looking at a 1987 P39-2 but it appears that there is a discrepency regarding the construction of the hull below the waterline. I have read 2 articles that say the opposite (one says solid fiberglass the other core at bottom of hull). Is there a P39-2 owner out there that knows what's what and can tell me how to identify the core in the hull. Would greatly appreciate this help
