Because we go so far from shore I made two "BC"s for each scooter with 40lbs lift each. I used TUSA snorkelling vests which are made from a very thick and tough material. It also protects the scooters from sand and rocks on shore and on boats they can be inflated to cushion the scoots from bouncing in rough water. A motorcycle bungee net surrounds them and compresses them into the body of the scooter. No appreciable drag but a great place to store bottles, shells and other ocean finds in the bungee net. On the upper photo the black thing on top of mine is a tank carrier handle from Trident which lets me carry the scooters one handed and works very well.
