In the previous pics. The anchor locker drain holes are 3/4 pvc glued in with a healthy amount of gorilla glue construction adhesive ultimate. I don't know how it lasts but seems to be pretty stout stuff. The panel is 3/4 inch honeycomb with a layer of 1708 on each side and a layer of Matt on the topside.. put a thin fillet down all the joints then used 2 strips of 1708 4 and 6 inches to tab it in. Had a random piece of 1708 laying around, that is what you see lam'd in the center bulkhead. It was there, I had extra resin, it got laminated. I hate wasting resin. Lots of random pieces of glass have been stuck on this boat. Did most of the inside of the rail with random glass and left over resin.
