forgot to mention would like to here from anyone with nasa wind instrument. Good buy, bad buy. Possibly another boat show item on the list.

Have had absolutely no problem with mine for the last two years, also have repeater at chart table and close haul display just fitted.
I believe it to be reasonably accurate and it is easy to operate and read. Requires two people to set up and should be set up while mast is stepped or someone is aloft in order to have it pointing correctly....there is a tacking function to achieve this but I am not convinced it would be very accurate.
I would have another one, it does what it says on the tin. But do check <A target="_blank" HREF=http://www.allgadgets.co.uk/>all gadgets</A> prices before committing to boat show offers, you might be surprised.

I have had one for two years, it has not been a happy experience. The display has been back to NASA twice for a problem with the screen fading to blank, still not fixed. The mast head unit has now stopped sending. Have not been up the mast yet to check if it is fitting or cable. I am so fed up with the thing I will probably bin it. Who needs the wind speed anyway, just stick your head outside!

Have had one for two years, no problems. Check All Gadgets for good prices and very good service.

NASA
Produce basic kit at very low prices.
Do no in-production tests.
Their screens are especially chancy - but what do you expect at the price.
However they have a good returns policy and, bearing in mind it's a small staff coping with a large volume, good on their customer service.
With regard to all wind instruments - from whatever manufacturer, they're all about x2 as other instrumentation to fail. They're complex and subject to considerable unfair loadings.
Don't rely on them, all offshore single-handers have at least 1 backup system (it's almost impossible to sail an Open without wind instrument) and none are NASA.

I would recommend that you look at the Silva dataset. I have been very pleased with mine, and it is on the same price level as the NASA range.

I had one a while back. One of the cups on the transducer fell off within its first year. Nasa refused to admit that it was their problem, and made me buy a new part. This was somewhat silly of them. For the sake of a small bit of plastic which would cost them only pence, I will not buy anything Nasa again.

We have one that hasn't worked since we got the boat.
I have a wee spindly bit NASA sent me for nothing (good price) with which I intend to attempt to fix it shortly.
But . . . if I don't manage we will continue to sail with two bits of wool on the shrouds and one on the backstay. We have outsailed similar boats with full instrumentation many times, and there are a lot of things I would buy before investing in a complete new wind system.

Alternative Wind Instruments
What do you suggest as an alternative/ backup then?
If the masthead one fails in the open, persumably you need a handheld to tide you over until you can reach sensible facilities (or it's calm enough to reach the masthead). Does anyone know of a reasonable priced handheld system? Or even a DIY design.. [my favoured option!]
Regards
Richard.

...Back of the neck???? Human skin is very sensitive to changes in both direction and strength... I agree totally with previous post.

Re: Alternative Wind Instruments
I have a conventional 3-part mechanical wind indicator at the mast head. Wind-speed I'm not so much bothered with
Most offshore racers mount an electronic anenometer and direction indicator at mast head and the backup on the radar mount pole.
