We got some good work done over the past 2 weeks. Reinforcements arrived from Florida and they were much appreciated. We were finally able to put something back into the boat.

Finished setting the molds, ground off the screws and got to work. 2 layers of CSM as a skin and 1 layer of 1708 to help fill the void. After this hardened we mixed some putty and filled any imperfections on the seam of new glass and original glass. Then a layer of 1708 over the entire width of the bolster to tie it all in. Hard board and wax worked better than expected, popped right off!

Next, all the coring material was bedded with "hull and deck" onto the cap. For the most part we used divinycell, except for the bow, mid ship and aft corners were we expect to have more stress (cleats/swivels), here we used coosa board. Then we sanded down the outside edge allowing the glass to lay smooth. Finally thickened up some poly and made our fillets on the inside 90 deg as well as the outside edge to smooth out the seam. All coring material is 1/2" thick, as stated before 1.5" gap from outside edge. To finish things off 1 layer of CSM and 1 layer of 1708 throughout tying everything together. A 3rd layer of 1708 was added in a couple spots around the coosa board sections.

Here's a bunch of pics. Pumped to see it on the boat. Topside still need some work.
