There is a fourth question:
4)What does an ultrasonic weather vane measure when a sailboat heels a lot?
A mechanical weather vane then always gives a consistent measurement in relation to the wind angle on the sails.
But with an ultrasonic weather vane, what's the mistake? No manufacturer communicates the error of its sensors tilted to the wind. The few racing boats that have tried ultrasonic sensors have found that these sensors are too damped. They then tested faster sensors but it seems that this was not satisfactory because regatta boats no longer have such sensors.
I tried to get information from the manufacturers who all refused, which is quite suspicious.
Some nautical magazines have tested different wind vanes, but always without any heel. It's weird.
In the meantime, I prefer to avoid having an ultrasonic windvane coupled with the pilote.
