- Installing Anemometer on Masthead - what should I expect?
I'm adding a Raymarine wind transducer to the top of my Hunter 28 mast this weekend I've already run the instrument wire inside my cabin through the existing conduit so I'm good there Our club is renting a lift for the weekend and I'm hoping to avoid stepping the mast entirely I don't know
- Anemometer is sluggish - Sailboat Owners Forums
The anemometer cups don't spin at low wind speeds and can sometimes take up to 8 or 9 knots of wind to start spinning Because of that I'm not certain how accurate it is either but mostly I would just like to get it to work in light air Is this fixable? Corrosion, salt maybe Pull the cups and spay with silicon? Does the masthead unit need
- Why anemometers - Sailboat Owners Forums
A thread regarding a non-working anemometer inspired this question: What is the purpose of knowing the wind speed at the masthead? I've sailed the Caribbean from the Florida Keys to Grenada, but none of the boats had wind speed devices and it never occurred to me to want to know wind knots
- lubricating anemometer bearings - Sailboat Owners Forums
Our TackTick T120 masthead wind indicator needs lubrication I've opened up the unit but the anemometer shaft is held in place by a small round clip (see photo) I have been unable to figure out how to remove it so I can clean and oil the bearings Can someone please advise?

The yellow wire is 5volt pulses generated by the anemometer Now, the MHU is fed 8vdc on the red shield There is a down-converter up in the MHU which converts 8v to 5v, and then uses that for the Hall Effect sensor on the vane At the base of the mast with the wind blowing, you should see 0-5 volt pulses between yellow shield
- Looking for a cost effective CFM meter for Dust Collector and Air . . .
There's no such instrument as a CFM meter, but you can measure air speed as Mike suggested and taking measurements at several points to get an average velocity and using the cross sectional area, you can estimate the CFM Don't forget to do the necessary units conversion from FPS, MPH, knots, km h, or whatever the anemometer is displaying to feet per minute Once you have this number, what
- Calculated Wind Speed Way Too High | Sailboat Owners Forums
We've got a Garmin anemometer vain tied into our plotter (I will look up the model when my wife wakes up and I can get to our manuals ) The only thing we really use is the ability for the system to estimate true wind speed and direction Kind of handy when we are motoring along at hull speed
- Cheap wind instruments - Sailboat Owners Forums
A few years ago, I built an anemometer on the cheap, using three table spoon measuring spoons as cups ($3) and a cap from a black spray paint can (free) This was mounted on a piece of old stantion (free) using a bearing scrounged from a dead VCR (free) and mounted on my stern rail using a BBQ mount I found in the garbage at our club (also free)
