Jerry (Piranha) Sez: These are photos taken inside the hull of my Cobra Fish-n-Dive showing the installation of monster fun noodles as flotation . They slip in between the scupper shafts and the exterior of the hull. I also have them in my Pro-2-Tandem. They add flotation should a mishap occur, with one running down each side. Many Fish-n-Dive owners have implented this inexpensive safety feature. Cost a little more than $5 each at Walmart in the pool toys/accessories section!
