The Potter people on the Trailer Sailor site who have converted to Lateen sails include: Harry Gordon - "Manatee" John Madill - "Mackinac Dreamer" Bill Nolen, former owner of "Piglet" The new owner of "Piglet" is Jim McWilliams in Castell, Texas. I have communicated with the first three and they are all nice people. Bill has a Yahoo group with some lateen information. http://groups.yahoo.com/group/WWPotter_Owners/ I think you can automatically join it. Go to "Files" then select folder "D: Potter Articles - Technical" There are three files in the folder of interest. * Harry Gordon's New Lateen Sail * P-15 Conversion to Lateen Rig * Piglet's Lateen Rig Conversion The last file does not have a ".html" extension on it. You will need to save it on your hard disk and type in the ".html" extension. Then click on the saved file and it should open in your browser and load the pictures. The e-mail addresses are in the files but if you do not spot them shot me an e-mail back. steve Steve R. M-15 #119 Lexington, KY
