iFLY15 with Heru Sails Wing Sail won
the “all Foilers category” @ Foiling Week
iFLY15 winning FoilingWeek in category “All Foilers”….after passing a 6 day training for the five new iFLY owners, some of them were racing in FoilingWeek regatta. In up to 20knots of wind, iFLY was showing stable upwind foiling with windward rake. The boat was flying at high speeds and good angles / vmg (speed regards to wind/next mark). On the downwind leg iFLY performed a couple of foiling gybes. The difference in speed was very pronounced, with iFLY15 going deeper and significantly faster than the competing designs, while fully trapezing and sail trim as upwind.
The development of this wing sail took almost a year and it began with the realization of a 14.8sqm wing sail on a 8.5mt mast; after many tests a final dimension was chosen: 12.5sqm on a 7.5mt mast.
With its 6kg, our wing sail is fully sealed and it is realized with a standard laminate fabric with aramid fiber threads, carbon and fiber glass battens, 4 sections with variable airfoil profile, medium twist for all around performance.
