I knew my name would come up in a discussion like this (thanks, Jake!). I do have a set of P18 sails that I was just about to put on eBay. eMail me at: danberger@mindspring.com and I'll send some pics and particulars.

The P18 is one of the best boats I have had! They are good and solid and just a pleasure to sail. However, some of the parts are a bear to find. I would start collecting rudder castings and rudders because they break easily and you can't find them when you need them..
