Capt. George Mitchell of Jupiter, Florida, fished the SKA pro division for years, in addition to being a highly sought-after charter captain. While on his boat during the National Championship in Biloxi, Mississippi, last year, he showed me a neat trick he uses to pressurize his livewells before making a long run. He makes small, sliding doors out of Starboard, which he screws in place over the overflow grill in each well. He slides them down, reducing outflow before making a run, and slides them open when he gets to his destination. It works like a charm, and his baitfish look as good at the end of the day as they did at the start.
