Ezzy Hydra Sport Quick Start Manual

Tuning the Hydra Sport
Calibrated Downhaul System
1) To set your downhaul:
a) Use the correct Ezzy mast combina-
tion and check that the length of your
mast falls within the recommended
length (chart 1). See "Troubleshooting"
if your Ezzy mast combination does not
match with the lengths in Chart 1.
b) Downhaul your sail until the calibra-
tion mark lines up with the bottom of
the mast (figure 1).
Which Calibration Line to Use?
- Powered up: use the MAX line.
- Medium powered: use the MED line.
- Under-powered, use the MIN line.
Additional Information:
- We have set the adjustable head
cap to the correct setting. Do not re-
adjust the head webbing.
- If you feel back-hand pressure, apply
more outhaul.
- If you are foiling, set your sail flatter,
with more outhaul and downhaul.
- To get the best performance, adjust
the downhaul and outhaul together.
For example, if you increase the
downhaul for strong wind, you should
also increase the outhaul. And, for light
wind, to get maximum power, reduce
the outhaul as well as the downhaul.
-The Hydra has been designed to
ALWAYS have a fold of material
extending along the luff from the #2
batten down to the foot batten.
