A Nettlenet Pool- also Keep the Kids Corralled?
Could this be useful for you? While it won't keep away sharks, these easy to use boat pools can be used to keep away stinging sea nettles or jellyfish, and also keep your young swimmers corralled, so they can't float away from the boat.
'Nettlenet in use'
.
Available in 8, 12 and 20 foot diameters, the eight foot deep, portable pools are inflated by a foot pump(included). The manufacturers tell us they 'launch in minutes and store compactly when not in use'.
Apparently the flotation ring is made of the same composite fabric used in aircraft life vests and life boats. When inflated, the ring has sufficient buoyancy to support the weight of people without becoming submerged anywhere along its length. It is buoyant and rigid enough that it remains circular and totally afloat. 
The netting material is attached to the flotation ring to form a continuous protective barrier, completely around and below. The mesh is small enough to bar stinging sea nettles, but open enough to allow water to move freely through it without acting like a sail or parachute. We are promised it will resist years of wear and tear.
