Wind sensor location

Hello all,
Sue and I have slowly been refurbishing our Cheiftain 38 (centre cockpit) and finished installing the new log and depth instruments some time ago. We had also purchased as part of the deal a new wind instrument and mast sensor. Long story short I was not able to get up the mast till last week to change over the instruments and install the new mast wiring. Once at the top of the mast I found that I was unable to move the old wind sensor cable and fearing that I may break it and lose its ability as a draw wire I suspended the job.
As the rigging has not been checked for some years and some of the halyards need replacing as well as mast lights I have decided to drop the mast in our winter to do this work. In the meantime as we have no wind instruments can anyone see any issues with me installing a 2 or 3 metre stainless steel tube off the pushpit and installing the wind sensor to this and running the cables to the already installed reader in the cockpit as a short term solution so that I have wind instruments. The old instruments were not functioning and were quite old. We have updated to Nasa cruiser range of instruments and have found them to be excellent at this time.
Many thanks for any assistance or advice.

Re: Wind sensor location

The correct position of wind sensing is the top of the mast. any other point on the boat will only show the deflected wind by the sails and never be correct wind direction.

Re: Wind sensor location

You can mount like you suggest however it may not be that accurate. I have a wind speed sensor mounted on the solar panel frame about 2m off the deck and it works most of the time. However the other week I noticed that the radar dome was just in the wrong angle for the breeze and the wind speed was easily 5-10kts out. 80% of the time its not a problem.

What you are suggesting is fine as a temporary solution. Like you suggest, longterm best spot is the top of the mast.

Re: Wind sensor location

I'd just leave it off until you get the mast down in a few months, then do it properly. Not like the wind meter is the most important instrument.

Guys,
I confess I'm with the others in thinking why bother when its only a couple of months until winter ? If you cannot live without wind instrument then maybe think about a cheap handheld device to get you by. Just seems more work than it is worth and as Ilenart notes wind speed at cockpit level is not all that accurate anyway.
