how much you looking in the aspect ration of the downwind boards?
as all board getting extremely long , seems to me that is important to compare them not only by visual shape but also by aspect ratio ( length\width)
for example:
Armstrong 8’2X16 3/4" - 5.8 AR
F-one 8’0x18" 110L - 5.0 AR
StarBoard 8’2x18" 100L 5.5 AR
Sonuva 7’6x18" 113L - 4.9 AR
James Casey discusses the idea of a foil ratio, with attached spreadsheet. Seems like a good idea but probably needs to be locked for similar AR or reconsidered with AR in mind
I actually liked the old Gofoil way of naming their foils. Although never explained by Alex Aguerra, the way I perceived it having own a number of them before they changed to naming by cm²:
The number represents the ability to lift someone at 15 knots on a same standard board.
GT140 : 140lbs rider
Maliko 200: 200lbs rider
Maliko 280: 280 lbs rider
Etc
And it was pretty consistent for various riders weight IMHO
i had some spare time so i upload all the boards i found online ,
this really give you good perspective on all the boards in the market , and help chose and compare boards .
Mabey next step is to add the board price?
