They are both pretty good chargers. Be sure to keep them dry. You typically see waterproof chargers in a boat like yours. Charles made great chargers but decided to pull out of most of their marine products last year. The Pronautic has more power output so I'd lean that way, but with 2 Group 24 batteries it wont make much of a difference. On some boats, the Charles 2000 series were know to introduce noise into the electrical system. The 5000 series had hardware to prevent this.
