Where can you purchase Float Tube Creels or Live Wells? I'm curious about how the tournament float tubers secure their catch for weigh in?

Stringers? (Not in salt water, unless you want to wrestle a 500lb Sea Lion or Shark!)

Fresh Water Baskets? (Still sounds risky)....Or due they make some customized, breathable "Hefty Bag" that hangs over the side of the tube. It is my intention "Someday" to fish tournaments from my tube, and that question has to be answered.

Thanks in advance for any/all assistance.
