When I bought my 21' Boston Whaler a couple of years back, it came with a removable baitwell that bolts onto the deck and is fed by a water pump on the stern:
A lot of times, this is a lot of baitwell to be putting onto the boat. I can see that if we're going out for a full day of serious fishing it'd be worth it, but a lot of times I just want a little live bait for a quick session on one of the local reefs ... and that baitwell takes up a lot of deck space, competing with dive equipment and other gear ... not to mention the weight of the water it holds.
Has anybody found a smaller, more portable bait tank that works well enough when you just want a little live bait? Would sticking an aerator in a bucket work?
