Yes, the boat is Certainly stronger than it was new, I layed the stringers in with 24oz woven mat, and I injected the foam under the entire floor as I layed it in, three sections. I was sure to see the foam had reached it's maximum expansion before I layed more flooring, and before I glassed it in, the foam added a Lot more rigidity to the hull structure, and only added about 12 pounds.
sooooo red, you've filled the hull with foam? how far did you go to get it up under the bow? looks like the boat is ten times stronger with full foam. do you have any picts of the install?
