I've done thousands of nm's on two boats using a
Hydrovane and concur with Robert that using the main
rudder as a trib tab is important. I also found large over lapping genoas are the enemies of the
Hydrovane, I've gone down to a 100%
jib for a couple of reasons, are yet to try it with the Hydrovane, will do so come May.
The type of
boat effects how efficient Hydrovanes
work. New bigger boats are faster in light winds and the
rudder can push the vane around, they now sell a extentable vain as a
work around. Surfing big ocean swells can be a challenge for the Hydrovane rudder as well. Where are powerful
autopilot can compensate for poor sail trim, reefing etc this dosent apply to the Hydrovane on a bigger
boat, you need to get the boat sailing well.
