2017 UltraSonic

The high performance light wind machine.

Designed around the concept of Ultra planing: maximum efficiency in the lightest winds. When there’s barely white caps on the water, the UltraSonic gets going and flies on the water. With every gust and every wave, you can tune the board to foil up and fly, picking up speed and passing lulls like they’re not even there.

The wide shape continues from last year with new, minimalist racing graphics and our new UltraCore technology.


The UltraSonic design starts from the iSonic base and loses more thickness for a wide and slim profile. The current shape is 7mm thinner than the previous generation for a wide wind range.

Heel extensions allow the back foot to apply a positive pressure on the rail. Without them, there would be a slippery angle of the rail and your back foot would fail to provide constant power.

The UltraSonic’s nose is also longer than an iSonic which makes tacking, jibing and getting going easier and more accessible.

The cut-away shapes, combined with the side cut-outs and heel extensions reduce wetted area for the same lift, which makes it more efficient. The fin gains traction and the board locks on to its fin.

Most importantly, the width of the tail remains identical to previous models to maintain the UltraSonic’s ability to provide power, anti-roll stability through chop and acceleration out of a jibe.

Under the footstraps, the rails are more comfortable and less boxy than on the iSonics. This makes the board more comfortable, the straps are easier to get into and there is less burning-power in your back thigh when fully-powered.

The 2017 UltraSonic is fitted with the next iteration of Drake UltraLight footstraps. These hydrophobic footstraps weigh 99 grams dry, saving up to 232 grams dry and 676 grams when wet.

Two new layers of Kevlar X-Ply monofilm replace the internal plastic strip to keep the footstrap comfortable, light and flexible but eradicate any stretch.

The zero tail-kick rocker provides a smooth entry into planing while making the board easy to control when fully powered up.



What is UltraCore?

UltraCore is Starboard’s proprietary sandwich core material that’s 30% stronger, 40% stiffer and 10% lighter than conventional PVC sandwich cores. UltraCore allows Starboard to build boards up to 1.2 kg lighter than our 2016 models.



The UltraSonic is supplied with the highest performance Drake Race 58 Ready to Race fin that generates massive power for early planing and outstanding accelerations in light winds.


UltraCore Hybrid Carbon Logo - Red - LR

We’re now offering the UltraSonic in two new constructions: the new UltraCore Carbon model that replaces last year’s Carbon model with a stiffer, crisper feel. We’ve stiffened up the board between rider’s back foot and the mast foot pressure, with four Smart Carbon vectors on the deck and a full Carbon Innegra perimeter band.

UltraCore Reflex Carbon Logo - Red - LR

On top of that, we’re also introducing a special series of UltraCore Reflex Carbon models. These are even lighter again. It is our very lightest technology built in the most exclusive, lightest grade biaxial carbon fibres on top of our exclusive UltraCore sandwich core.

Every millimetre and every gram of the UltraSonic has been designed for one purpose: ultra-efficiency in lighter winds.
