It's really just the boats that are in anyway difficult to work with, and that's because boat movement and system health don't really exist in land games. Actually, for full-on naval battles, it's unclear whether you even need to have infantry miniatures, since even boarding actions share the abstract positioning of fights in buildings. I guess having minis around makes for cooler pictures and easier wound tracking. Yet it also makes Blood & Plunder one of the few games where smaller bases are absolutely better.
