E34-2 Mast height? (really, total length)

[N.A.]

Hello folks-

I have someone running cable for my mast, and they want to know the total mast length. Of course, they need to know... now, and I... can't find the number. Of course I know my bridge clearance is < 53', but what is the mast length? It is keel-stepped, below the waterline.

--> I need this for an E34-2.

Per sailboatdata.com, the 'P' boom-masthead measurement is 39.0 ft. (and that has worked when I got a new main, so must be right), but I don't know where to look for the actual total mast length. [N.b., my boat has a Lefeill spar, not a Kenyon -- it was built by Pac Seacraft. Unfortunately, Lefeill no longer sells spars, so it is hard to get numbers for the mast... but everything else matches the E34-2 specs, so probably this too.]

I can find here, from Tom Metzger, that
"Based on the rig layout drawing in owner's manual on this site (my note: manual for an E34, not 34-2 I think) I found the mast height to be 44' 4" above the coach top and that the mast is buried 6' 8" below the coach top. Therefore it is 51' mast. I scaled the drawing and found the mast goes 15" below the water line. Allowing inaccuracies, I am confident the mast is less than 50' above the water, not counting the anchor light, antennas, etc."

I would like to know the heights of bridges I can pass under. Thanks Steve

But here I see 51' clearance (where I got 53'... I do not know. But better over than under

--> If anyone has the actual number, it would be very much appreciated!

Oddly the manual gives the (Kenyon) spar cross section, etc., but not the actual length.

Many thanks!

Don't know the exact length but last year I installed a B&G WS310 wind pack on our 34-2 that came with 66' of cable. It was more than enough to make it from the top of the mast, thru the starboard settee and to the nav station.

Thanks! Mine (a Raymarine wind pack) apparently has to run all the way back to the readout unit at the helm. I think that's why the person is asking -- the run is pretty long.
[I'm not entirely sure why it has to go to the helm; there is a repeater at the nav station. I think it has to do with my choice of the helm unit (i60 vs i70 display)]

I would have to say, looking at all the tools the guy brought to the boat (and appears to be using) I am feeling pretty comfortable with farming this one out to a pro. I had been a little unsure, given the cost and since I do understand electronics pretty well given my profession, but... running the cables? Mounting stuff to an (atypical) pedestal? I can already see from what he's been doing that I would have experienced a lot of frustration, lots of delays as I went seeking yet another specialty tool, and probably made some expensive mistakes.

Agree. when our spar was out for 10 months for the re-fit, our ship wright installed all new pvc tubing in the spar for wiring and replaced the wiring. We did re-use the Raymarine wind transducer and wire. He has a lot of experience over the decades and did a great job with the wiring on top for both stress relief and also for sealing.
I was the unskilled helper , and did drive a lot of the pop rivets for securing the new tubing to the inside of the spar. I seem to recall that our spar section is over 55', but even if accurate does not help you any...

I have my backbone at the nav station. Wind transducer cable goes to the backbone, data is then fed to the MFD at the helm.
