Many boats (including mine) safely have FLA batteries in the ER below the main salon. The engine room is vented anyway and FLA still delivers the most AHrs for your dollar compared with AGM & Lithium per Jim Healey over on the MTOA & AGLCA forums.
I agree in sleeping spaces, best to use AGM (that’s I what I use for my thrusters) but two 4 D’s cost more than my 1100 AHr FLA housebank.
