Maugan, you are correct. Hobie did the 17, 18 & 21 with the S&S blue hulls (trophy blue), white hull caps, black mesh tramp and R/W/B sail configuration. Some had variations in the color panel placement, large block USA on the sails and a special numbering sequence.

Does anyone know how many models of each were made? I saw a S&S TheMightyHobie18 on ebay a couple months ago.
