Karl,

Find a proper marine charger with independent outputs.

There are lots of them available.

The one in my boat is a Xantrex Truecharge 20/40 and has three
separate circuits and an optional remote status panel and battery
temperature sensor.

You are going to have an awfull time charging the batteries on your
boat at sea with that unit. That is a "shore power" charger.(unless
there is a major feature not described in the brochure, or I realy
missed something)
