Longitudinal cracks in ribs: Glue and clamp, or lamination necessary?
by Dom Elias

We're restoring my South Coast One Design (SCOD) yacht (mahoganny on oak, 1956) and I had an idea for an alternative rib repair:
I know that usually cracked ribs are repaired by laminating/sistering/steaming of replacement ribs.
When the crack is across the rib, I see no other alternative.
Yet, for a crack along the grain of the wood, could gluing and clamping be an alternative option?
As you can see from the picture, there is plenty of material on both sides of the crack, the wood is solid on both sides.
My plan of action would be to remove the rivets first (planks in question are going to be replaced anyway) plug the holes with wooden bungs, epoxy and clamp, then redrill for the floor brackets when (re)fastening planks.
Maybe it should be said too, that the rib in question is one of 12 ribs holding the 6 metal floor brackets
So my question here is: Is gluing longitudinal splits in ribs an option you have heard of? Done it? Have a good argument for/against doing it like that?
