Re: Board surface
- I only approximate the area of my boards by simply multiplying the
board length by width (max width I think). Since most kiteboard sides
are pretty straight this approximation is not that bad until we can
get the TRUE surface area from the board manufacturers.
Using the same approximation, your 2 boards are 4514 cm2 and 5246 cm2.
My favorite boards are actually approximated at 4370 cm2 and 7267 cm2.
I am around 60 kg. based on the board surface formula, if I had your
weigh, my favorite board would be around 4885 cm2 (or 122 x 39 cm);
however, my light wind board would be 8134 cm2 (much bigger than yours
- this may explain why I can go out in much lighter wind)
P.S. When I can go out with a 16.6 m2 kite and a 7267 cm2 board,
another kiter weights 75 kg should be on a 24.9 m2 kite and a 8134 cm2
board (179 x 45.4) ... This may explain why I can go out in much
lighter wind and the others can't ...
