To my surprise I saw that both the ultrasonic and the isonic 91 have disappeared from the 2020 starboard range. The same pattern seems to exist at the rrd range as well and I suspect fanatic will follow suit. This is really disappointing since the ultrasonic is the board I love most and the one that has drastically improved my windsurfing days. I have emailed starboard and wait for a response but I suspect all major brands are pushing hard on the foil fad and want to make us invest a few thousand of our hard earned money on foil ready boards and a foil quiver. Shame because I am not keen on following the foil craze any time soon and it seems I will have a hard time finding a replacement for my beloved ultrasonic when the time comes...
