On my big boat, I have a Prosport battery charger that is many years old. It is a smart charger. It can put a total of 20 amps to any battery, not the 5/5 like the Guest. It can put 2 amps to one battery and up to 18 on the other. The charge floats depending on what each battery needs. It is one of the best small chargers made.
Either way, be sure to get a waterproof/explosion proof unit. Especially if you are fishing in salt water.

This how most of your better chargers work. Gives more juice to the battery that needs it the most until they even out.
