turning circle and wing size

Postby neilhapgood » Tue Jun 11, 2019 1:10 pm

hi folks,

just wondering is the ability to make a tighter turn influenced by wing size?

I currently have an f1 mirage 1000cm wind and i am struggling to get it to turn tight enough to keep line tension going to toe, is it a case of trying to drive harder like you would a sb or 'twist' harder from the hips, and as I mentioned above are bigger wings harder to get a tighter turn on?

thanks

Try driving hard with the back foot in tight carves. When the foil is really canted over on its side, the back foot push will make the wing "pull up" and tighten the carve.

Wing design, mast length and even board swing weight play a role in how tight you can carve, but technique also goes a long way, so you can likely get a tighter turn without changing anything.

Low aspect ratio probably more important than overall size.

If you’re just learning to jibe to toeside and you’re having trouble keeping line tension through the turn, it’s almost certainly a problem with your technique and not yore wing. Your 1000cm wing should go plenty slow to do this.

My take on this, having sizes on my 7 wings from 520 to 1200 cm2 both low and high AR:

The smaller the wing, the more lively it is, period.
The lower AR, the more lively it is when bigger sizes.
The bigger it is, the tighter you can carve, for two reasons, more lift, and lower speed.
And again, bigger wings with lower AR, the more lively.

A small wing which is lively feels "good" somehow IMO, but the speed it needs will kill the narrow turn.
A big wing with low AR feels okay lively (not as much as the smaller ones though), and can turn narrow - so a good, the best, compromise for turning tight.

A big wing high AR is not as lively, but it can still turn really tight in my experience, as once you have initiated the turn, it goes just as tight.

Remember the "Yaw" input when turning, this is essential the bigger the wing and the higher the span, it changes the turn dramatically to the "tighter".
Dont drive harder, if your problems is line tensioning - use your hips as you say :thumb:
In more wind you can drive as hard as you like, and also use a smaller more lively wing if you like, but in lighter stuff where these big sizes are used a lot, initiate with the yaw impulse.

So yes, a bigger wing turns slower, particularly if higher span (AR).
But slower turning does not mean bigger turn radius, on the contrary, that is the paradox if this makes sense?

Fully agree... use your hip movement like on a skate board when "tic-tac".
