Mast Down or Up for New Wind Instr.

replacement.

It will cost me almost $550 to de-step and restep my mast over the winter. I hadn't planned on it, but last year I did it to replace halyards and a windex. Well when the yard restepped the mast they bumped something and misaligned the windex, so that was pretty much useless. Over the summer my Datamarine Wind Instrument has decided to start to fail. The wind speed is okay (I think)) but the indicator direction is messed up. It is off by 180 deg. I tried to recalibrate, but with no luck. It is also slow to respond to wind changes. I am thinking of replacing it with Raymarine ST60+ Wind Unit.

I'd rather not unstep the mast to install, but will need to replace the cable and the masthead unit if I decide to go this route. Option one is to climb the mast and pull off the Datamarine unit and pull out the cable with the new cable spliced in to the other end of the cable. I would then install the new masthead unit. and complete the assemble on the ground. I have never gone up my mast and weigh about 235, so hauling me up isn't easy. I could buy a solo climbing set-up, but that is almost as much as unstepping and restepping the mast. The other option is to unstep/restep and work the whole thing from the ground.

Thoughts?

Thanks.

If your boat is on the hard, you will be much safer unstepping the mast. Do NOT go up the mast if the boat is on the hard, unless you're using a cherry picker crane or platform lift to do so.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Boat is currently in the water.

I know not to go up mast on the hard. Want to understand if trying to do fix/replace a mast head sending unit is doable while possibly sawing back and forth. If not, I'll unstep the mast.

Thanks.

Yes, it is doable from a boasun's chair, but it is far easier to do with the mast down...

DrB,
Just as a side note, I also have old Datamarine instruments that have seen better days and am looking at these for replacements.
Sail Boat Instruments!
I like that I won't have to make new cut-outs.

I had a yard install a raymarine without unstepping the mast. Some marinas have platforms you can do this from shore, others doe not. This is one way you do not have to climb a mast...........Otherwise, yes it can be done from a bosuns chair or equal.

I have all Raymarine gear on the Dehler. Never again. Their wind instruments are a joke. Bird lands, system is toast or at least needs someone to go up mast for repairs. High wind comes along, likely the same outcome.

I forget the name off hand but there is a company that makes wind instruments without the silly little exposed whirly bird gizmo. Next time I am by the goodie store I will get the info if you like or maybe someone here knows. I believe their masthead reader can be hooked up to ST60 so the whole unit will not have to be replaced in my case.

To make life easier take a look at thiswind instrument. From what I have seen it is reasonably priced compared to other units.

I have TackTick and seem t be the only one who has had persistent problems with the syncing of the masthead transducer and the display. The outages are now transient and tolerable, but it took a replacement of the transducer to get there. When it works, it works fine. There's a slight delay, which may be attributable to the LCD display. The display is also wireless, BTW, so the installation is about as easy as it gets.

I see folks go up the mast on the hard all the time. If you go straight up, what's the problem?

I'd go up the mast while it's in the water of course. Cheap and easy. No need to buy $500+ worth of gear to go up a pole. Wear sticky gloves and shoes to 'help' the grinder, and go on a diet. Better for your heart, and the grinders.

Or find someone lighter to go up the mast. The instrument itself can't be that hard to install.
