Larger wings for larger guys.

Postby diogovilla » Fri Jun 05, 2015 6:08 pm

Hi,

Besides using larger boards, will we see larger guys using larger wings in the future?

Hydrofoil wings can generate lift in one of two ways; speed or wing area/characteristics (such as aspect ratio). Speed is more efficient, as that value is squared in the simplified lift calculation, while area is not.

In light wind, lower speed applications (to include wave riding or free riding in wind speeds of 3-5 m/s), wings with greater areas will give one option for getting the required lift for a heavier rider.

As for a current real world example of a company addressing this, Moses offers their free ride wing in 425mm and 450mm widths.

Reference this thread from BraCuru (Moses Team rider) and they suggest the FR450 for riders 100 kilos and up: viewtopic.php?t=2388923&p=889807

Of course larger wings are needed for larger riders, and opposite for lighter ones :thumb:

Just like with "normal" boards, different sizes used because of weight differences.

It is not proportional though, as larger riders use bigger kites, as they get more vertical lift from the kite.

Because of this, the difference is not huge, but with huge weight differences, it will be there.

Brands often have a big race wing and a smaller one, so to some extent the riders will just "change" size at a different wind speed, if different weights.

I dont think we are talking about "the future", as larger riders ARE using larger wings now (just as larger kites of course) :rollgrin:

Hi Peter,

I am not thinking on race wings. I'm thinking on all beginners buying their first foil. They are being offered "freeride wings". Should those wings be available in bigger sizes for riders like me (>100kg)?

I don't think it is necessary, a bigger board might be interesting to start easily
but a big standard freeride wing should be ok for your weight.

On my case I started with a big wing at 80kg and I have seen quickly that I need a smaller wing
to ride faster and to foil in more wind.
I still use my big wing for very light wind, with your weight you will probably need 1 or 2 extra knots but it should be ok.

(I have an alpine foil)

why? because you are the statistical 75kg or you have another influential reason in mind?

bigger kiters use not only bigger kites but also bigger boards. in some cases size of the board is more inportant than the size of the kite. with the so called "high performance" kites you don't have any significant "vertical" lift. don't try to fool the public!

water is much more dense than the air.
heavier rider has more advantage of using the board with more buoyancy/lift than just with using kite with no powerful profile (eg "high performance")

Sorry, you lost me there ?

Heavier riders use bigger kites, and bigger boards, and bigger wings - is what I said, although not proportional to weight as a vector sum of all (eventhough the board size is not important once up foiling - but kite size and wing size is) :D .

A performance kite (max upwind and of course only foil kites) has a lot more power than both a high power or a low power (flat profile) tube kite, and besides, heavier riders typically use tube kites with more power, compared to lighter riders - for the same "feel" and control.

Could you clarify your point with above posting - sorry, I didnt get it :roll:
