Hi, looking for a reasonably priced servo pendulum wind vane for my 26' Marieholm IF, located in Berkeley, California.
A Navik, even with missing/broken parts, would be ideal. Also considering Wind Pilot Pacific Light, South Atlantic s-301 or one of the smaller Flemings.
Track the guy building Sindbads. He may be still around. His windvanes are good and new.
For the time being you can still deploy a s/h windsurfer mast with a vertical vane. This will drive the tiller OK. Imprefect, but zero cost and works (most of the time).
You will likely pick up a decent windvane along the way. Bargains do pop up.
