Even this won't work Jeff, because of the way sail numbers are assigned. Blocks of numbers are assigned to the various manufacturers (that's why you don't see 105000 series sail numbers in the US - they were assigned to Europe)

And whose to say that numbers weren't skipped? There's another thread in the Hobie Forums about how Hobie "lost track" of the sail numbers on the 14's and were putting numbers that were 10,000 off from what they should be.

They make a lot more sails than boats.
