Hello, I was wandering if you could give some advice. I have just been given a Pearson sailboat. I don't know anything about it. The Certificate of Documentation states that it is a 1975 30' 9" Pearson. I am new to the sailboat world and am having a hard time finding info on this boat. There is plenty of info out there but nothing for a 30' 9". Would you please help me to find what model Pearson I have? This is what I do know: 30' 9" Wheel Helm Yanmar Diesel (probably not original) Center Board Head with shower It needs work but I can't find any of the original specs. Any info or advice would be much appreciated.
