There was delamination at the floor beam-to-hull attachments, probably due to earlier groundings and we could also see the swinging/pendulum keel symptom when the boat was transported with the keel hanging. It was time to do something about it. The plan is to reinforce the whole keel-to-hull joint with 3-4 layers of 600g biaxial fiberglass cloth, re-bond the floor beams to the hull with at least 6 layers and add new structural members to stiffen up the construction against side loads. This is how the delamination looked like: In the fall of 2019 we started the keel/bilge reinforcement project. It took several weekends to sand everything and it was probably the most difficult boat work (or any type of work really 😃) I ever did. I killed one orbital sander and one vacuum cleaner during the job. Then I bought a cheap vac with HEPA filter from Biltema, which turned to be a really good choice. The high density filter is really a must to catch the very fine fiberglass dust.
