Slack line with water
I picked up some good slack pointers on a visit to Cal city a few
years ago -- where they really do slack rope (rotor)!
- Yaw/spoilers are about stopping the slack from getting bigger. Once
the slack has stabilized, you want less drag not more.
- Get to a bit above and to one side of the towplane
- As the slack is about to come out, bank slightly towards the
towplane, and nose down a bit. Presto, slack out with no worries.
- The slight bank towards the towplane is the most crucial part of the
maneuver. If you bank away from the towplane, you're like a kite and
will slingshot. I really recommend testing this: watch slack come out
with 10 degress bank toward vs. away from the towplane. The difference
is amazing.
- The last-minute yaw of the glider away from the towplane is not a
good idea. It does nothing for CG gliders, and it is a violent
sideways pull on the hook for others. If you're off to the side, the
towplane with much longer moment arm will do far more sideways
movement than you can hope for anyway. Yawing away from the towplane
makes it very likely you will bank a bit away from the towplane too,
see last item. Finally, you want less drag at the moment the rope
comes out, not more.
I haven't had huge slack with full water yet, the main question here.
It would be fun to hear from ridge/wave types what their experiences
are.
