Thanks for the comments guys and GA that holder is VERY high tech,,,,,,hold a piece of plywwod up to the back of the boat, trace the shape and grab the jigsaw then screw it to an old set of wood horses,,,,,,,told you VERY technical!
Surely someone in the starmada has a formula,or good notes, for how many swim noodles it takes to fill a 16' SS. If not lets start a pool and take guesses. My guess is 60.
Zero- I use foam board and get more flotation per $. And more flotation per cubic foot also. My opinion.
