Will someone please enlighten me on the construction of mast step? I see basic fiberglass on the outer section? Any wood involved? Underneath, is there a big block of epoxy/resin and glass just bonded to hull? Anything under this block, or is load directed to hull only? I can see some previous repairs that have lasted a long time and are pretty solid, but its really tough to tell exactly what is in this area. Any input would be great. Thanks
