Warning: This post will include numerous "newbie" descriptions of electronic equipment.

My electronic wind gauge is sitting about 20-25 degrees off center at the top of the mast. A couple of weeks ago I went up the mast and realigned it, but within minutes it quickly returned to its original incorrect position. There didn't appear to be any screws or things to adjust on the unit so I thought all was well.

So... I'm back where I started. Is there any way to make the unit work with this sitting 20-25 degree off up the mast?

I've been fighting with this for a few months now and am quite frustrated with it. Any ideas? Is it time to just give up on it?

Thanks!
Bryan

If you supply the make and model of the wind instrument you might get a response.

The condition you describe is obviously not normal, and there either has to be a way of adjusting it, or something has to be broken. If nobody here can provide you the specific information you need, I suggest you take the mast down and examine the unit more closely. Perhaps you can find the solution. If you were able to adjust it, but it failed to stay in place, maybe the addition of a lock washer or locking bolt will help keep it in place after you adjust it.

Need the model info however if you look in the manual, you may find a parameter you can change to set a "position offset" value to compensate for it being off center.

Our Raymarine wind transducer (vane with a wobble) almost fell off once. The nut securing the support tube at the top of the mast became loose while we were on the water and the guage was only held in place by the tension of the electrical wire. It still worked just fine. If the wind were very light, then the angle would probably not cause too great a significant error (the wobble weight would accelerate downhill but slow up hill).
However the wind angle would certainly be off if the transducer was rotated. If it is twisted but rigid, then you can just calibrate it for the correct angle.

Can you take a pic of the attachment point as well as provide the model info.

Paul

My Marina told me that the mast on a Catalina 25 was only climable by someone weighing less than 100lbs. Did you ascend in a Bosun's chair, and, if it's not an indelicate question, how much do you weigh?

I have had people weighing 200lbs up my mast twice. We used a canvas ladder that is hoisted up the kerf.
