Thank you for the additional explanations. Opening up the the fiberglass over the keel joint at all/ any water ingress into joint is definitely the concern, as you mentioned Joe.
I found what seems to something like scrap fiberglass/ hdpe board around the marina. But, the pinkish brown color doesn't match any color of coosa board or King starboard or any other type of such board that comes up online. Can anyone identify this is? It seems heavier than wood. I added a couple pictures to the end of the album here https://photos.app.goo.gl/fnTpJJrbdAQ8htiH8 The idea of lowering the sole in the walkway was something I've had in mind separately to get more headroom. A few more inches maybe. Haven't looked into the feasibility. Thank you!
