The rotacectra does not have both vindwane (to measure wind angle) and the cups (to measure wind speed). Rotawectra has a fin on one of the cups and somhow calculates the wind angle. Don't ask me how this is done, but the cups are probably slowed down/speeded up by the fin in scertain angle which makes it possible to calculate the wind angle. Raymarines normal wind transducers have both the wane and the cups (like most normal windtransducers). I would not use a rotavectra to drive a autopilot in wind mode, and I would not use it on a sailig yacht to make tactical decisions either, but that just me.

Has anyone had any experience good, bad or indifferent with them and are there any reliability issues with them? Discussion seems to be a little off topic. Obviously nobody is using one or has direct experience. Summary: Raymarine in spite of what Doug says does not have a non-mechanical transducer for sale. If so part no please! Certainly nothing on their web site. Non-mechanical transducers are used in a number of commercial/military applications but not prevelant in recreational boating. My application is for a wind system to fit im with my Raymarine ST60 system. I have seen enough dud mechanical transducers to not want them on my boat. Therefore I'll wait. -- Regards, John Proctor VK3JP, VKV6789 S/V Chagall |

They did when I worked for them.

Thanks for your explanation.
As motoryacht owner wind speed is more important as direction.
