Navik Windvane, missing part ?

[eebygum]

Finally got the Navik all installed on my Contessa 26

But in installing it all together, with help from the manual there appears to be one peice missing ! (I purchased the item 12 months ago secondhand and while we put it up in the sellers garage the missing part would not have been apparant in his garage out of the wind !)

The unit below which has the windvane and counter weight on and which which sits on the vertical SS pipe seen in the picture above should sit on a SS pipe which fits inside the vertical tube ?

If you have one of these my question to help fabricate the missing peice is:

How long is the inner SS tube ? the full length of the Vertical tube ?

Is the tube a loose fit of fairly light ? assume not too light as it it does not need to rotate

And finally do you please, please, please have the dimensions ?

Thanks in advance and I guess this will only make sense if you have a Navik !

Cheers
Andrew

Had the navik on my last boat and unfortunately for you all the handbooks went with it otherwise I could have found you the part number. Do not despair though if you try Seateach they may be able to pin down the number for you and order the exact part.
As I remember it the part you seem to be missing is a stainless rod that links the vane gear to the trim tab which in turn gets the pendulum to move.
Its a great little windvane and worked perfectly on my Halcyon 27.

One question do you have the small plastic connectors for the rod? they join onto the small stainless rod with the ball end fitting you can see in your second picture and there should be one for each end.

Compared with mine, the tube you are missing is made of a green plastic (grp, I think) presumably for light weight. I shall measure it and send you a PM.

I have used the Navik for 18K miles, including northern Norway, and found it a great bit of kit for a small boat. It has proved remarkably durable, but you do need to carry spares of the bits that wear most, the plastic links.
It is wise to reinforce the paddle-blade around the hole which takes the s/s pin when lifted and parked in the frame as that is where they break when overloaded. I applied a 'glass-tape and epoxy' bandage around that area, then re-drilled the hole and re-shaped the extra bulk at the leading and trailing edges until it fitted into the frame again.

Thanks guys, Sent you a PM Piota

Scillypete, from the B&W picture in the manual yes it looks like SS but I believe it's no more than a central support column to hold the windwane..... I have the thin green plastic rod which goes down the tube; with the connector on the top to provide the pendulum motion (I think !!).... if I need to fabricate one I was thinking of finding a light GRP tube of the right thickness.
