Thanks ya'll I'm aware of the cons. Fixing the currently shoddy
installation would require more time than I currently have and my proposed solution fits all my needs on a day only sailor. My only non
engine related loads are lights and don't get used unless on
shore power hanging out at night.

It most definitely is weird if you actually saw how the previous owner wired it up. Not only would I not be any worse off than if I only had one battery I would be approximately 672% safer than I currently am.

relevant quotes from link -
"Over the years most all
boat builders, of both sail and
power, have installed the simple and redundant 1/2/B switch. The switch, I believe, has gotten an undeserved bad rap over the years. Why?
It’s really not necessarily due to the switch itself, but rather due to the way most builders install them, and the way many boat-owners have used them."
"If you wish to continually move the switch from 1 to 2 then 2 back to 1 etc. etc. it may feel like you have a START & HOUSE bank
but you really don’t. In the #1 or #2 position each bank serves both starting and house purposes. Starting and House services cannot be isolated from one another with a 1/2/B unless you add another ON/OFF switch."
