Centreboard removal 26C

Having listened to sound advice at the zoom meeting I decided to remove my centreboard to check it ...
And this is why you should check the centreboard once in a while. The cables were frayed, the leading edge is badly damaged. Only been painted where is drops down in the trailer.
Please see pictures ..

Any advice welcome! I'm assuming the pairs of holes top and bottom are to let water / air drain in and out?
(Also having made a 9/16 bent spanner discovered the nuts were not that size .... so I have 2 bend spanners now)

The method of securing the up haul is weird, See photo of metal fabricated bolt (2 nuts welded on studding) with a groove round it, the s/s cable runs round the groove and back up to the boat?

Do you know the length of the cables? I plan to make a template to let me find the length required to get the centreboard exactly vertical and then make the second safety line 50 longer. Does that sound about right?
I also plan to put a 2 : 1 pulley in line to ease the "tug" on lifting.

Last time I dropped my fin

Last time I dropped my fin out, which was a few years ago now... I went and got new fittings and cables from bluewater, or ruddercraft.

If the nut wasn't 9/16, then make sure it is the correct material. Someone has swapped it at some point!

And I think the nut is nylok, so should be replaced anyway?

They had been changed to M10. New nylok nuts is very good idea. Bizarrely the bolts still use an imperial Allen key???

Made a simple template to determine the cable length required to hold the centreboard vertical, hope it worked as all back installed, with new s/s wires ...

Chris,

Chris,

There was no way I could have change the line with dropping the centreboard. Having said that, you needn't remove it completely, you just need to access the lines attachment on the trailing edge of the blade. This could be achieved by raising the boat enough (6ft?) to drop it normally - though not practical unless you have access to a hoist. I have also read that some have raised their boats using jacks enough to drop the blade. I was surprised how narrow it is, only about 12 inches, so not much clearance is needed.
Having gone through the pain of getting the boat high enough to access, I'd still advise taking the blade out to service/paint and fill, I was shocked at how much damage there was the the leading edge.
Remember to take a note of the length of the line so as to replace with the same length, hence I made up a template to get this correct.
