This is getting real, fast!
I got into the port side sheer strake today and it is in worse condition than I expected. I removed the toe rail and uncovered plenty of rot. The worst of it is in the rear quarter as you can see in the following photos. I cut out the rotted end to the closest frame and exposed the internal structural components. Fortunately the clamp and frame are not rotted. You can see the remains of the iron bolt I removed sitting on the deck the large hole to the left is a good example of the result of iron sickness.

My idea is to sister a cleat onto the frame to serve as one of the attachment points for the replacement piece. I will then dovetail the existing end of the sheer strake and fashion a new piece to fit.


The following pictures show the rot that was under the toe rail. My plan is to rout down about 5/8" along the entire top of the sheer strake and glue and screw in a new piece of white oak and reshape it. I expect that the starboard side will need similar treatment.
