iFLY RAZZOR Pro – Efficient Foiling Dynamics in Ultra Light Wind

This video showcases the exceptional aerodynamic and hydrodynamic efficiency of the iFLY RAZZOR Pro in ultra-light wind conditions. iFLY achieves stable flight and high speeds where most foiling craft remain stuck in displacement mode. Taking off in light wind is not inherently difficult per se. Even low-tech boats can lift off with sufficiently large sails and oversized foils. The true engineering challenge lies in combining early takeoff with high speed, superior flight stability, and precise control — and maintaining this performance consistently across a wide wind range. The iFLY RAZZOR Pro meets these demanding criteria through: – Active foil control system FlySafe® – Advanced foil design and construction — on a technological level comparable to SailGP, TF35 and America's Cup foils – Mainfoil Differential T-Foil (MDT) — increasing righting moment by actively using the windward foil for downforce. The mainsheet stays tight, using the windward foil to create downforce Unlike conventional designs that rely on brute-force sail area and oversized foil area to get airborne — often at the cost of speed and control — the iFLY RAZZOR Pro maintains efficiency across the full wind range — from light breeze to strong winds over 25 knots and rough sea states. This makes the iFLY RAZZOR Pro truly unique in the sub-35ft category. Comparable performance is only found in the admirable TF35, a marvel of high-tech engineering, and in the elite ranks of SailGP’s F50 and the AC40/75 foiling yachts. On the small-boat stage, the foiling Moth remains a benchmark for light wind performance and agility — though it caters to a very specific and extremely skilled type of sailor. The same applies to the impressive foiling A-Cat.
