a sphere is around .5 something like that but a cylinder is somewhere around 1.2 something like that, correct me if I'm wrong. also typical cruising speed of a kiter is 20 knots so you want to compare 20 knots to 33 knots something like that. I just now from personal experience I start feeling the drag on the lines when you get above 50 meters.PugetSoundKiter wrote: ↑Tue Jan 14, 2020 10:57 pm
Drag = 0.5 x Drag Coefficient x Area x Density x Velocity²
Drag Coefficent of a Sphere = 0.48
Kite Line Diameter = 0.0015 m
Line Area = (200m x 4) x 0.0015 = 1.2 m²
Air Density = 1.225 kg/m³
Velocity = X m/s
At 9.7Kts, 5m/s
Line Drag = 8.82N = Weight of 0.9kg or 2lbs
So at 13.6Kts, 7m/s
Line Drag = 17.29N = Weight of 1.76kg or 3.88lbs
So at 15.5Kts, 8m/s
Line Drag = 22.58N = Weight of 2.3kg or 5.1lbs

Maybe you have a marine layer or the wind is doming so there's some wind at 100 meters blowing 30 knots and at Sea level it's blowing 1 knot. Sure then it's great. But maybe it's blowing 7 knots at Sea level and 8 knots at 100 meters. Then no it does nothing the extra drag would make long lines worse than short ones.
Go make some 100m lines by tripling some line sets you understand better. It's something fun to do on a light wind day but in terms up practical use I put it up there with stacking kites.
50m lines are useful above that usually not so much
Good catch, you’re right.edt wrote: ↑Wed Jan 15, 2020 1:33 ama sphere is around .5 something like that but a cylinder is somewhere around 1.2 something like that, correct me if I'm wrong. also typical cruising speed of a kiter is 20 knots so you want to compare 20 knots to 33 knots something like that.

Turning speed is always the same.
