The foil sections are designed for low stall speed and high maximum lift, with very low drag over the range of lift coefficients for pumping but still maintaining low drag at higher speeds. Combined with a high aspect ratio platform they have amazing early take off and exceptional glide, but still maintain a good top speed and upwind ability.
Anhedral geometry allows for easy carving into tight turns despite their relatively high wingspan, and tip detailing allows for breaches without crashes.
They are great free-ride foils for all conditions; they can power upwind quickly and then glide back down on the smallest of bumps, they can carve up larger waves and they pump very well.
