Kane was riding a Signature Stealth in that video , very different to the long skinny wings , more like the MFC 1075 cm2
Finally got some GoFoil GL measurements to make some comparisons.
GL 180 :- 960mm wide x 163mm cord ( seems to just as good as 210 & faster)
GL 210 :- 960mm wide x 190mm cord
GL 240 :- 1066mm wide x 215mm cord
Axis 900:- 900mm wide x 175 cord 1277 cm2 ( Kai is apx 1200 cm2 ) ( Naish Large 1236 cm2 )
Axis 1000:- 1000mm wide x 175 cord 1388 cm2 (Iwa is apx 1600 cm2) (Naish XL 1572 cm2 )
The Signature 210 Albatross 1355cm2 is very close to the GL180/210 & Axis 1000 . Out of the 3 , Signature & GF are flatter and faster but the Axis is not far behind with more wing curve giving it slightly better turning ability. These were never designed as surf wings but for DW but they have made their way into the line up. The Signature 210 is nothing new it's actually a re badged Uni Foil so the design is close to 2 years old , it's just now riders ability have caught up to this great foil.
You can see by the above comparing the Axis 1000 to a Iwa . The advantages of high aspect it simply gives heaps more speed for way less surface area. Simple Physics you want a boat to got faster simply reduce the wetted area , same goes for a foil.
Thanks for this Piros. Informative as always. Just to add... I've just measured my Unifoil 210 (signature 210) and its 950mm wide x 168mm cord. That puts it far nearer the gofoil GL 180 than the 210 and would make sense based on pics Ive seen (GL 210 looks a lot less high aspect than unifoil/signature).
There's a unifoil 190 on the way apparently. It will be interesting whether they reduce width or chord to achieve that reduction in surface area. At 68kg I cant say Ive ever felt too much lift with the 210 (at least on a SUP... on a prone I use 175) and that now makes sense now I know it's very close to the GL180 in size.
