another anenometer question

[Windfall]

Sorry to be a pain --- but what a great resource this forum is!

I've estalished that I can cut and re-connect the transducer cable & my local friendly chandler is sourcing the right connector for me (or is this just another cunning marketing ploy?). But this morning (not working today just dodging the kids instead) I had a mooch through the Raymarine web site and am worried to discover that the transducer cable should not be run within a metre of a VHF cable.

Argh! So what do I do now? Both the new aerial and the wind whizzy thing are sitting proudly at the top of the mast, can't possibly separate them by the required 1 metre...in fact the only way to get them down the mast was by pulling them through together - and what a job that turned out to be.

Any comments gratefully received.

Thanks
Sharon

Dont worry about it. I've got exactly what you've got (and so has probably everybody else) and it works fine.

There is nothing you can do about it so ignore it!. I have compared new instructions for raymarine autopilot with an earlier version, and note that there has beena dramatic increase in the required separation of wires and electronic equipment. I suspect that this is a liability waiver (i.e. it is not our fault sir, you did not install your **** in accordance with the instructions). IMHO, these equipment manufacturers know how we will be installing equipment (most boats have similar equipments in similar positions) so if their equipment will not work in those circumstances then it is not "fit for purpose".

I'd agree with the earlier replies; this is just a cya statement by the manufacturer. Unless you have a ketch, you haven't got much choice unless you want your VHF antenna or the anemometer mounted lower down (which isn't much use!). I would guess that 99% of yachts have the units mounted and cables run within 1 metre of each other. So, don't worry.

I have never had any problems from running NMEA/Seatalk and VHF cables together. Both Seatalk and NMEA (the data formats used by Raymarine instruments) are robust against interference. Their lowly data rates help.

Two cases where I have had interference though...

A depth transducer cable didn't like being next to the power cable from an unsupressed power ouput on an old outboard.

My autohelm doesn't like mobile phones too near, sends it into a random frenzy when a call comes in.

Is this requirement to comply with the EC E.M.C directive? Otherwise, unless they are marketing the product entirely for use in ketches/yawls, the restriction seems preposterous.

autohelm used to be british but they are now part of raytheon, from the land of the rising lawyer.

why do you think that garmin gps sets have a screen telling you that any data is for reference only?

your next new boat will have a sticker saying that it is not guaranteed to float and must not be used in water. /forums/images/icons/wink.gif
