2025 iSonic Windsurf Board

Flying at high speed, the iSONIC 60’s tail becomes the only surface touching the water. Our race development focused on refining this area, explicitly aiming to increase control while decreasing resistance. The more comprehensive forward outline provides balance and maintains a perfect, powered racing stance while maximising confidence and control in strong winds. Behind the foot straps, a narrower outline optimises trim while reducing critical drag at maximum velocity. The combined outline improves glide, precision and planing speed through tight turns, ensuring better acceleration back to top speed. The iSONIC 60 development involved extensive rough water testing in Tarifa by Matteo Iachino and Blanca Alabau. The result is an absolute open-water high-speed DefiWind weapon. iSONIC 60 is ideally matched with performance carbon fins around 32cm.

Development of the new iSONIC 63, already renowned for a compelling low end, targeted extending the high-end wind range and enhancing the more confident, locked-in feel. The 2025 evolution maintains the tuck line, whilst a more comprehensive outline and volume at the back foot straps help engage the more powerful leeward rail. Lengthening the centre rocker flat by 7cm extends the limits of control, keeping the iSonic 63 trimmed level and comfortably controlled at full power, even in overpowering conditions. Together with iSONIC 60, the new 63 was proven in the rough chop of Tarifa by Matteo Iachino and Blanca Alabau—ideal with a 33cm carbon fin.

iSONIC 67 stands out as a reference of the best slalom board we have ever made. Adding a 1.5cm wider outline in the tail drastically improved efficiency and speed in lighter winds. The new Arrow tail cutaways, similar to the iSONIC 73, allow the board to fly freely over chop. The most exciting feature of this board is its exceptional control. No matter how windy or choppy, the nose will never fly away. You have to try it to experience how good it is. It’s the perfect medium size board for light riders and women.

Versatility meets speed. A breakthrough 2025 design, with increased width to 73cm at the widest point and a massive 2cm added at the rear foot straps, while leaving the tuck line untouched. This change gives you more power in lighter winds and critical situations, jibing or overtaking your friends. Or competitors. As the wind picks up, even more release - thanks to the rear focussed stance and our new Arrow cutaway design at the very end of the tail - less surface in the water and higher top-end speeds. You will be blown away by how much control you can have while flying this new board design over any water surface.

Developed in the lighter winds of Thailand together with the 85, the iSonic 77 optimises rider stance and mast track rearwards, freeing the ride while improving fin leverage and easier control. Everyone was simply faster on this version. The hip outline combination ensures more performance in light winds, where the windward side of the board is more in play while also improving competitive jibing. iSonic 77 adds confidence in stronger winds, most especially when harsh chop starts to compromise speed.

With foils becoming a genuine challenger to the big slalom boards, our most notable detail in the iSonic 85 is the increased tail width, enhancing low-end power. The powerful tail section also provides significant control improvement; as the board starts to fly away in strong gusts, the tail section becomes activated, and the nose trim stays lower, ensuring optimal control. And performance. The tuck lines remain unchanged, while tail cutaways in line with the smaller iSonics make this large board feel super loose under your feet.
