I've seen people using "bait sleds" (I think that's what they're called) -- boxes which are towed behind the boat, cracks wide enough to allow the water to flow through. (Not sure where you'd get one, but I think they used to have them for the rental skiffs in King Harbor, Redondo.)

If you want it on board, probably the best bet is to make your own. Get an ice chest and a 12 volt aerator to blow bubbles to keep the water good. (I've seen this used to carry anchovies from one pier to another in the back of a pickup truck, so it ought to work in a small boat.) The ice chest lid will help keep the bait (and water) from slopping out if the ride is a little bumpy.
