what gauge wire for rewiring boat

Time has come to tidy up the boat wiring and get rid of some of the tangled mess of wires from add-ons over the years. Does anyone know what gauge wire would be suitable for all the electronics nav lights etc . is it better to go heavier gauge to be on the safe side from voltage drop . Im talking about the wires from a buzz bar to the individual units . Also is it better to run Eco Sounder direct from the battery or is it ok to run from buzz bar as well. At the moment it runs from buzz bar but turns off every time I start the motor
Thanks Paul
