Realize that your batteries will lose aprox 10%-20% of their capacity in the first year, and on top of that your 440 amps (which I'm interpresting as AMP-hrs) only about half is actually usable. What you are saying can be done, just make sure in the end you will get what you need. A marine electrician may not be a bad person to callon for this. You will also want to make sure your alternator can handle the charge demand.
Regarding the above post, beware, temprature controlling chargers will usually monitor the first battery only, and if the second or third go out they will overcharge and boil your batteries. It happened to me, We woke up at 5 am with the nastiest smell inside as our batteries were boiling out their acid.
