Update:
Made my cat walk 24" wider after falling off, all is well I have a hard head. I made a 1" ID fiberglass tube to go in my limber holes, glued stringers in, attached bottom to stringers, Cut in bow thruster hole in the first bottom layer thinking if I screwed up I could cover it with the second layer. It fit just right not afraid to say I was a bit nervous about it, then glued on the starboard side bottom second layer, cut off the ends of the bottom and stringers.
With the Kodiak having taller sides than the typical GA I won't be attaching the sides until the bottom is completely finished. With the catwalk it is so much easier to get to the bottom for glassing and painting. When I install the sides the bottom will be finished up to 3-4" from where the sides meet the chine. I'll be using Sea Hawk 2145GL Tropikote Black Gl for my anti-foul bottom paint. Very spendey at $250 per gallon but from what I could see it is the best out there.
