Hi,
We lost our mast (long story), and are having a new one built. We lost
everything except the boom and mainsail.
Our previous wind instrument was a Navman 3150 which we had for a bit
over 3 years. In that time I had three new display units (under
warranty) because the LCD segments went all funny intermittently. This
meant is was unreadable for speed, the direction was OK.

Anyway, I don't want to go through that again, so am after
recommendations for a new unit.

Thanks

We've had really good results with B&G instruments on Lionheart. Ours are
now obsolete, being the "Network" series which is a daisy-chained NMEA 0183
you can pull data out of by just connecting to its data wire anywhere in
the loop. Some of the B&G instrumnets on the Amel Sharki 41 have been on
it long before we got it. Lightning got the wind head before we got the
boat. I could tell because the bearing in the anemometer was welded
together. Even that didn't kill the unit! We got a new head and replaced
the wiring inside the mast and it works fine, now. I like its ability to
be calibrated by instructions in the manual. I'm sure the new units are
similarly adjustable. We have units WIND - SPEED/LOG - PILOT
(electro/hydraulic autopilot with separate compass sensor) - DEPTH - DATA
(repeater at the nav station) and they all work great after I cleaned up
the wiring from the rats nest the previous owner made.

B&G, being British, should be quite popular in Australia, too, which helps.

I have had no problems with Autohelm/Raymarine ST50 instruments and there
are lots of replacement parts on eBay for cheap prices. I imagine the newer
ST60 and ST80 instruments are just as good. My latest boat has Standard
Horizon instruments and I noticed they fogged up in really cold weather.
Could not read them. B&G are good but, I think, expensive and you will not
find cheap replacement bits on eBay as easily.

As another Aussie you may want to think outside the square;-)

First as you have already found out stay away from Navman. I used to
install marine electronics as a job and they are just plain junk! Sorry
but that is the truth.

Second, stay away from B&G they are expensive (e.g. a new mast head
unit is about $1300 AUD). Also remember that Kongsberg bought them out
like they did to Navico and over time they sank like a stone. B&G have
great instruments if you are a professional racer with deep pockets!

Third, I don't know how many mast head units we had back at the office
but there were a lot! Bearings frozen, missing cups, vanes broken and
just downright savaged units. Given that land based weather head units
have gone to heated wire, ultrasonics etc with no moving parts it seems
to me that this low maintenance technology is highly appropriate for
the marine application. Yes the motion of the mast head does complicate
things a bit but the software should be able to compensate. There are a
few of these units on the market but widespread adoption does seem to
be limited. The average life of a mechanical head unit is about 3 years
(notice I said average) so replacing such is not an onerous task until
the wiring in the mast goes and then its fun.

Just my 2 cents worth.
