BlockP I sail a P19 myself and the total crew weight it carries is 225KG (496 lbs) or 185 KG (407 lbs) depending on who is crewing. She holds up well. Some time ago i found some photo of three guys sailing a P19, I think it was at the TheBeachcats.com hope you forgive me the hijack. Harry could you tell me more about Your P19 conversion, Did you do anything else to accommodate the squarehead sail? And how much of a difference has the change in sailtype made?
