The iSonic Speed Specials are the pure speed needles of Starboard€™s range. Technically advanced designs, they are reserved for the best of speed sailors who know what they need to go fast. Not just the feeling of going fast, but knowing that speed is the result of meticulous GPS measurements and the combination of hours of tuning with perfect riding expertise.The two middle sizes, the W49 and W54, are designed for consistently fast runs throughout a wide range of conditions. These are the typical choices for speed riders on the tour. The largest size, the W58, is quite wide by speed-board standards. It is designed to deliver the highest possible top speed in relatively light wind conditions. The W44 is designed for one purpose in mind: the absolute highest possible speed on a windsurfer. Ultimately the Starboard€™s fastest boards. For speed experts competing on the race tour, for GPS speed sailors and for Bjorn himself.
