Have made some progress lately on internal members, centerboard, and centerboard trunk.
Don't have the internal structures glued-in yet, but I finished the centerboard trunk piece today so I think that will come soon!
Have coated both the inside of the centerboard trunk, plus the entire centerboard, with graphite + epoxy mixture to try and minimize friction / binding in the rotation of the board. It starts off very shiny and the sands down to dull grey.
