I will be fishing a tournament in my lake that allows live bait. There will be two people in the 1256 Lowe V Hull boat. we modded the boat to have a casting deck on it. I want to have a way to fish live bait and for it to be out of the way of our lures. any help is appreciated...

Not exactly DIY but these are very good quality.  I have six in my boat.

I've made DIY rod holders with PVC pipe, but the above holders are far better.

Cabelas has these to mount on the gunnel if needed and then you can use their own rd holders.  It depends on your boat which type of mount works.

I ended up taking a milk crate and zip tying 4 12" sections of 1.5" pic, work realy well with the minnow bucket to weigh the crate down, i placed it at the front of the casting deck!

I will be posting four of these, I think, that mount to the inside below the gunwales.  They came on my recent project and I do not need them.  They will be available for postage.  There are no rod holders, just the mounts themselves.
