PLANING MACHINE
Designed specifically for maximum light wind efficiency, it is longer than the regular iSonics to quicker glide on to the plane. When foiling, it makes them more forgiving as well. The footstrap inserts and less boxy rail shape compared to the iSonics also provide a more comfortable, less powerful stance.
ROCKERLINE
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. The zero tail-kick rocker provides a smooth entry into planing while making the board easy to control when fully powered up.
CUT-AWAYS
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 provide power, anti-roll stability through chop and acceleration out of a jibe.
HEEL EXTENSIONS
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.
RAILS
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
DRAKE RACE 58
The UltraSonic is supplied with the highest performance Drake Race 58 Ready to Race fin with a quick and efficient foil and a near vertical rake angle that generates massive power for early planing and outstanding accelerations in light winds.
DRAKE ULTRALIGHT STRAPS
The 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 layers of Kevlar X-Ply monofilm replace the internal plastic strip to keep the footstrap comfortable, light and flexible and eliminate any stretch.
OUR MOST INNOVATIVE TECHNOLOGY
The UltraSonics are available in our new construction designed for the lightest weight but also the lowest carbon footprint; Natural end-grain balsa covers the bottom of the board, providing the board with its overall stiffness and reduced weight. The full sandwich deck uses natural uni-directional flax fibres with carbon stripes to reinforce and stiffen the most stressed sections.
