Matter of safety.. Why not a solar charger. Should do the trick and safer.
This unit is not a charger. If you meant by your question could you leave this on a charger?, I would not. I would disconnect the unit from the battery ( one terminal would do ) then hook it up to charger. I would not like to subject the multiple circuits to the possibility of over current.

This battery power center (battery case) is, by design, intended for outdoor use. So sitting out on your dock is fine.
But your battery charger should be an "on board" battery maintainer type.
That type of unit is made to charge batteries outdoors on boats.
Others can short out and be dangerous in damp conditions.
