Newly purchased Mk III, and wondering about the combination of the windpoint guage beside the companionway and what looks to me like an anenometer mounted on the masthead. (Made by Signet Scientific.) As far as I can make out, they are connected (8-pin connection from the device to the cable in the mast and again through the cabin roof). According to the previous owner it was not working. In any case, I can't see how the masthead device (which doesn't pivot, and has spinning wind cups) measures windpoint; speed, sure, but the gauge doesn't show that. Can anybody enlighten me on this one? I've seen the identical gauge on another 27, so I'm guessing it was optional/OEM. Additionally, is it worth rehabilitating the thing? Anybody still use theirs? Just about to step the mast, so I need to make a decision about hooking it up.
thanks, richard

Signet still exists, so you probably could have the thing fixed. However, most electronics seem to have a definite "best before" date and this unit may be as old as the boat. By fixing it, you may just be climbing onto a treadmill. Do you need wind speed and angle or are they just nice-to-have? You may be better off removing this unit and replacing it with the instrumentation that matches your sailing needs.

I have the same instruments on my 1982 model. They work fine. Giving wind speed and direction. The amemometre provides speed and the vane the direction. It is worth installing at least to find out if they still work. My boat came from a yard were masts are stored up during winter. The previous owner installed it without a disconnect at the mast step since he couldn't imagine ever taking the mast down (doh!) After taking a side cutter to the cable and installing a junction box for a disconnect. ...the thing still works. So they are relatively tough.
You're lucky, Cassia. We had them on a boat I raced on in the eighties and they were intermittent within two years, then functions just sort of fell off the table permanently.
Perhaps we had a bad unit - Hinckley 'burns in' new instruments before installation, running them continually for a month (which is only appropriate at their price point).
Or it could have been a bad installation. An electronics tech once told me that instruments don't fail, installations fail. This is one of the finer examples of talking rather than walking the talk I've ever seen, since his installation on at least one boat featured wires through the bilge, household wire and Marr twist connectors. Fortunately, he didn't support any of the wire properly, which made it easier for the owner to rip out.
