Deck: The deck lay-up was two layers of 9 oz 8-HS S-glass on the inside, and two layers of 10 oz 5-HS carbon. The middle third of the deck also had a external layer of the 9 oz S-glass.  Some 3 oz Uni-directional carbon was used to reinforce regions near the cockpit, including the decks forward and aft.
The first attempt at sealing hatch openings. With all the glass, carbon, release cloth, flow media, inlet, exhaust, and bag film in place, the hatch openings leaked. The final solution involved cutting through all that stuff, and glassing the covers in place.
Finally, adequate vacuum, not perfect, but as good as it was going to get. There were two inlet lines, closed with spring clamps. The C-clamps were closing off vacuum lines. When the infusion was complete, the main feed was closed, and the two vacuum lines opened to remove excess resin from the feed side.
Infusion in progress. The black line shows where the resin front was 12 minutes and 30 seconds after opening the resin inlets
Expanded polystyrene foam was used to build curing box. An Omega process controller (bought off e-bay) controlled a small electric heater to speed the gel time and provide elevated temperature cure. The drywall scraps prevented direct heating to the stern. A small fan in the cockpit maintained air circulation. I was concerned about the how the “mold” would survive the recommended 125°F cure temperature, so 100°F for 8 hours was all it got.
In the cooker.
