I was speaking of pleasure boats. USCG can throw 4 - strapping young 22yr olds at the problem if they need to move an 8D.
Similarly when you get into really big yachts the rules are different...again, the guy who buys a 150ft mega yacht likely is paying someone to bring big strapping guys in to move batteries around...plus they are likely putting them in a walk in engine room, not shoe-horned into a tight spot where you have to crawl in on your belly.
Pleasure boats below 50ft...almost unheard of (at least in the last 30-40yrs) and certainly with the advent of cost competitive lithium.
But all way off topic for a guy who doesn't even boondock. A basic group 24 is plenty for that use.
