I am in the UK and have been given a dinghy mainsail that is lashed to a plane wooden boom. I guess the boat would be about 12-14 feet long. I am searching for the type of dinghy. The sail has the letters YP (joined together, and slightly sloping to the right) with WW underneath, again the letters are joined.
Any Ideas as to the dinghy would be most welcome.

Unfortunately neither of these appear to have the logo you describe.....

Thanks for trying 'Faster'
I had checked those sites as well, that's why I was hoping the others members might be able to throw some light on it.
