This was fairly typical use on our sailboat:
Basically "wet camping"-- batteries charged by alternator 8 hours a day when in transit. Once in the Bahamas, at anchor/mooring. 2 4D Lifeline AGM's. largest draws were 12 VDC refrigeration unit, interior and anchor lights. Engine run 30 minutes AM and PM to recharge and make hot water (engine produced hot water). 120 amp alternator and Xantrex smart regulator. 30 minutes would just get into absorption phase with charge rate dropping to below 30 amps.
Yes, occasionally we had "marina days" to shop, do laundry, etc and were on shorepower overnight.
Batteries lasted 2 round trips (3 years) Texas to Bahamas and an additional 3 years. Just replaced this year with more Lifeline 4D's.
