The first day's run from noon to noon was 240 miles under full reacher and reefed mainsail, with surfing speeds up to 18 knots. It only demands one thing, in common with other windvanes, namely that you sail your boat balanced and in proper trim. In that sense, it was not only my greatest companion, but also my most useful critic during my forty-day odyssey from San Francisco last summer. No vane gear, servo-pendulum or other, features such expensive and seaworthy construction. The advantages are obvious.
Corrosion is avoided.
The material combines great strength with comparatively light weight. Everything is easy to take apart and, in the unlikely event of damage, repairs are usually possible, even at sea or in remote places. This four point attachment is extremely strong and rigid. At the same time the installation is very easy to perform and can generally be handled in a short time. The vane gear can be removed very simply by unbolting four bolts, leaving only the small universal brackets on the hull.
