Day 1

I went to the local building supply store and purchased 2 pieces of 2" builders foam (1-2 sheets short but wasn't sure of structural design), 1 piece of 1/2" foam, and 2 tubes of foam adhesive.

I laid out all the measurements for the pontoon core, cut them out and glued the top two pieces together creating the top of the pontoon, a 4" tall X 6" wide X 12' long. Cut the bottom and outside pieces on an 8 degree bevel, and cut the 1/2" spacers. I glued them all together and they are drying.

I still need to purchase one more piece of 2" foam for the insides of the pontoons.

After I cut out the inside piece I will glue them all up creating the two pontoons.
