I have also seen those batteries used for home security systems used. They are sealed and less bulky. You don't make too many friends on a partyboat if you insist on standing still (not following your fish) and reeling up everyone elses lines up with your fish every time you hook up. Being mobile can be a big plus. If you are on your own boat, or a charter, then use a deep cycle battery, just use a handcart if needed.
