Finished the core of the final (aft port) beam, so we get the satisfaction of busting up the beam mold. The plans called for 3/4″ particle board, but I think OSB sheathing would have worked better. Particle board chipped and split too easily.

Ian answered my question about orientation of the DBM1708 (tape with red stripe in it) – I should have been using the non-backed DB170 cloth instead. Got a 100+lb roll – that has made covering the aft beams much faster.

We received 800′ feet of one-foot wide carbon fiber rolls this week, and the first layers went on the bottom of the Forward Starboard beam today. Amazing to think they’ll be getting 20 layers of carbon on the top side!
