Thanks. Given all the negative comments about the NASA MHU I was wondering what options there were.

For what it's worth, I installed a NASA wireless wind instrument at the start of the year, and so far so good... it even survived Hurricane Ophelia!

My NASA wind speed/direction lasted about 8 seasons before the mast-head unit failed. I was pleased to discover that the mast-head unit can be bought separately but even more pleased that NASA repaired the old one very reasonably (I seem to remember for about £25). The service was excellent and the guy I spoke to most helpful

There was a good article in PBO a few years ago. Someone bought a new unit mhu, removed the spindly spindle and replaced it with a thicker one, then drilled out the cup unit to suit.

If only Nasa had as much engineering prowess!

Another happy NASA Clipper wind user here! I have had mine for 13 years and it's still going strong!

I had a NASA that lost its cups. Like others, got good service from NASA in replacing it. The current cups have survived 2 years intact, but last weekend I noticed the wind direction indicator was jammed. I wonder how that could happen ...
None on my mast at the time. That was a neighbour's.
Looking around the marina (Hythe, Southampton Water) I noticed that the starlings seemed to have a preference for perching on wind instruments, whether electronic or just pointers. At least they weren't perching on the cups themselves, but I wouldn't put it past them.
I guess it's a trip up the mast for me to see if I can re-seat the wind vane. Perhaps to fit a Windex or similar. In the meantime it's wool-on-the-shrouds time.

The windward ones attached to the shrouds are always in clear air. The leeward ones are (obviously) wildly wrong. I always hated craning my neck to see the windex. Tell-tales in the shrouds are much better imho, and no expense and nothing to go wrong.
