Thinking out loud...
I've been casting about for a while on ways to simplify the battery system on our 37 year old boat. We haven't changed anything other than buying new batteries about five years ago, buying a Hamilton Ferris 100 amp alternator, and putting in a SmartGauge.
Badger has a 4D wet cell starting battery and four 6 volt wet cell golf cart batteries in series parallel, controlled by three 1-2-both-off switches.
I was toying with the idea of a single house bank and spring starter. While that would remove the need for a starting battery and reduce complexity, it would be annoying having to wind it up in cramped quarters.
Thinking further outside the box, I looked at Genius Boost lithium ion jump starters. They barely lose charge in a year, can be used dozens of times between charges, can be charged in a few hours through a 12V cigarette lighter, and have USB and phone charging ports.
One bank. No complexity. Backup starting via the Genius Boost. Top choice of batteries would be 12V Firefly carbon foam because they aren't as sensitive to sulfation or to deep discharges.
