Our 1993's original sail # was like 307, replaced by a sail ~ 1998 (#532). Somewhere abouts 1998 to 2000, Hobie changed from the original Elliot-Patterson (E-P) fuller cut sail to a Hobie manufactured sail which is a much flatter. Look at the sail, if the E-P sticker is in the first panel, she's an oldie. Also look for delamination or pulling apart at seams.
Check the transom for serial number to identify exact year of hulls. Last few digits will identify year (i.e. CM...xxx97F)
