Centerboard cable

I have macgregor 26 1995 with swing keel whose keel retraction cable rusted out. How, where is it attached to keel and what's the best way to replace? It comes into cabin via rubber tube and attatched to a rope going over two pullies into cleat below sink. Any tips?

It sounds like you need a much longer line than I do though. I looked quickly on Rudy's website, and he doesn't have an Oday 30 centerboard pennant pre-made. However, I bet if you give him a call, he can tell you exactly what you need. In case you didn't know, Rudy worked for Oday for many years, and now owns the molds to some of the boats and their components. Rudy is quite the Oday guru.

Thanks for all the info.
Very helpful.
And yes, I did talk to Rudy in the past and he is certainly a great help for O'Day owners!

What do you use to attach the line to your CB?
A knot or an eye splice?

delan I have a 44 with a swingkeel, we swaged a stainless cable right onto the keel five years ago, no signs of wear or corrosion yet

TQA Hope you don't mind my hijack,

I have a 44 footer with a swing keel that extends my draft from 5'6" to 9' 6"

The keel weighs about 300 lbs Swings on a pivot and is held up by a wire cable wich runs through a tube to the deck round a pulley to a halyard winch mounted on the deck.

The load on this cable is significant due to the configuration of the cable attachment being about 18 inches away from the pivot.

I know I should have replaced the cable on my last haul but had other priiorities and on first inspection thought the cable was OK and would do another year but on refitting it on the day before my splash I noted two or three broken strands where I formed it round the eye.

The current cable is 7 x 19 stainless. My question is should I replace it with the same? the last one did at least 7 years.

But the books say use galvenised wire.

Or would one of these new types of rope be better.

merc2dogs WDS, I thought I was the only one who used lanolin

On my old trailer sailor, the fastening point for the cable was worn/rotted so it was elongated with maybe 3/8th inch solid iron between it and the edge. I had a friend come over and weld the hole closed, re-drilled it slightly over sized, then used a pair of nylon(?) flange bushing in the hole that were a snug fit for the shackle pin. There was no metal to metal contact anywhere from the cable, it was metal to plastic to metal. I bought two sets of bushings, and checked them every year before first launch, but never saw any wear.

The bushings were made and sold as a replacement for sintered bronze 'self lubing/oilite' bushings, and were supposed to be just as durable, advertising seems to have been correct

With low cost no-to little stretch line available now, there is no need to use steel underwater (like for centerboard pendents) or where the line requires handling (like halyards). I use sta-set for my centerboard pendent, and it lasts longer than the shackle fitting.

I would think between 50 and 80 lbs.
It is not a straight up and down CB. It pivots around a large pin (1 to 2 inch) that slides up a track as the CB goes down, and back down as the CB goes up (does that make sense?).
