Re: Centerboard repair-Bristol 32
Thanks for the info on your repair-in-progress, I have not found much info on repairing the centerboard cable systems on Bristols (or any other boats). Yours is very detailed and thorough, thanks.
I am in the middle of repairing the centerboard cable on my Bristol 29.9. The system is similar but most of the components are fabricated in fiberglass instead of bronze (except the shivs themselves) and the two shivs are in separate "knuckles" that are connected by fiberglass pipes, one directly above the centerboard connection, the other just behind the engine. The system is controlled by a winch mounted inside the starboard cockpit locker, with the handle inserted through the locker wall in the cockpit.
Anyway, my repairs have required me to cut open the shiv knuckle above the centerboard and the pipe just at the exit of the second knuckle by the engine. I had to do this in order to get the new cable run through. I tried various other "fishing" methods to pass a line through the system without cutting but could not prevent the fishing line from coming off the shivs and jamming thus preventing the new cable from being pulled through.
I have decided to go the Amsteel route for the new cable, using 1/4 inch rope. I spliced an eye into it at the centerboard end. My understanding is the only weakness of amsteel is lack of UV resistance, which is not an issue for this job. Rotting should not be a problem with this rope.
I do not have the same kind of damage you show in your pictures, just a replacement cable is all I need for now. However I can see potential for having to replace/repair the bronze shafts the shivs run on in the future.
I should have the whole system back together and sealed up by the end of this week, and the boat back in the water mid-April. I'll report back on how it is working with the amsteel cable.
Best of luck.
