Here's the view of the Port pour; I used King Starboard on both starboard and port sides with biaxial cloth epoxied to the starboard after the fiberglass cloth was applied to the starboard using Scotch 8005 adhesive after flame tempering the Starboard (see earlier photo). The idea was to pour the foam, get it expanding, saturate the underside of the shelf and the biaxial cloth covering the Starboard. The exothermic reaction of the foam set up the epoxy very quickly, so this was kind of a hectic operation.
This is really a picture of the first attempt; I actually ripped out the board and dug out the foam while it was still expanding (got a nasty burn out of it too! The exothermic reaction of the foam gets very hot when it expands in a small space).

My question is: if you pour foam into a confined space, what are the caveats? I have a void of about 1.5 ft3 between the keel mold and the upper deck mold housing the fuel tan, an area about 19" long 12" wide 5 = 6" deep. I have cleaned out the cavity and resealed it. I would introduce the foam (SeaHawk) though an 1 1/2" opening.
If I can controll the temp (boat is on MV) do I risk distorting the deck from pressure? Will the foam penetrate into cavities on either side of the keel?
I have kept a record of the process so far but have not been successful in posting it. How did you do it?
Would much appreciate your comments. E.S.
