Well after some poking around I've found that the damage to the keels is worse that I initially thought. Delamination extending up to around 4" from the keel bottom in more than one place. Each was hiding quite a bit of water and revealed some scary soggy wood on the starboard hull. Time for disassembly and a trip to the shed. Element needs a new pair of shoes. I plan for at least one layer of 6" 1708 biaxial tape possibly two, and a layer of 6oz in there for good measure. Here are a few pics of some of the worse off sections.
