I probably should. I leave the boat from time to time for a month or two in the hands of someone else who looks after her. When I am not on the boat, I will switch to "1" (my house bank) which leaves my Start ("2") only available for starting the engine, so if something was to happen, or someone unknowingly leaves this or that on and the HOUSE goes dead, the engine will still start. So I guess the current setup gives me options ... more House Ah when I'm aboard, and a little piece of mind when I am not. cheers, John
