3 Batteries and Switch

[bcguy]

I would like to hook up 2 deep cell, and one cranking battery (total 3 battery system) for sailboat with 50 hp diesel. Just wondering if there has been a thread I could refer to or would appreciate a wiring diagram for this and the best battery switch (all just for starters) in this process (the basics). I have simple boat set up with panel for vhf, radar, running lights, anchor light. Also have cabin lights... no frills like refridgeration, ssb etc. PM is fine. Many thanks
