Maybe I have overlooked it, but if building out of ply are both 18mm in thickness?

If you look at page 63 in the great how-to-build-a-boat-for-beginners you see:

22mm thick template for wooden centreboard
18mm thick template for centreboard made up put of 3 layers ply

And both rudder and centerboard could be made of 18mm ply.

I would recommend to make the centerboard in 22mm version, since that is longer and probably has better performance close winded. I think the rudder could be made out of 18mm ply as well as 22mm wood.

MIK??

Sorry, i misread your question

I first made a centreboard out of 3 layers ply but i didnt like the feeling of it. It look too weak to me and also feeling to weak.
So i decided to build both out of wood.

The solid wood option to finish 22mm thick is much better for both strength and performance.
