The live well in my boat wouldn't sustain my catfish and I didn't like the room a cooler took up. I built this floating livewell that I used to keep the catfish alive for tournament purposes. Also nice to cull fish at the end of the night. I was asked about it and thought I would post it for all to see. I used a rubbermaid storage container and put pvc pipe along the side of it for floation. I put small holes front and back for water circulation. I made a wooden frame inside to help give it strength and support. I have used this for about four years now. I can pull this around behind my boat at five mph. Kinda crude, but works great!
