Here's my top speeds (GPS) on some of the boards under consideration. Free Formula 138 (96 cm. wide) with a 20.5 inch True Ames weed skeg - 35.1 m.p.h. iSonic 122 with a 17 inch True Ames weed skeg, 33.9 m.p.h. - both with a Retro 8.5. The FF138 is a true early planer and is quite fast for a board of this width.
Of the twelve boards I presently own the Free Formula 138 and iSonic 101 are two of my favourites. My fastest board to date is the iSonic 87, but I don't get to sail it very often.
