the podcast I linked above is way more detailed but a few of the benefits they mentioned for boats are:

1.)    variety of how / where you can install your batteries. Lithiums are way more flexible since they don't have the water cells with caps. Old style batteries must be kept upright 

2.)    much faster charging 

3.)    no need to trickle charge. You can charge it up 100% before you leave for the weekend and then you can unplug it. You don't have to keep the battery plugged up to the charger that is connected to AC. Therefore smaller chance of a battery or charger over heating. Less chance of a a spark in an area (a boat house) that is probably enclosed and probably has gas fumes or at least gas stored nearby. 

4.)    better performance - the podcast goes in to way more detail and most of it is way over my head. But they gave a lot of practical examples, especially for fishing boats that use batteries for trolling motors, power poles, etc.
