ABYC standards require the battery switch to be as near the battery as possible so turning it off disables as much of the circuit as possible. The same standards also require the battery switch to be readily accessible so that it can be shut off in an emergency such as a fire. As the boat gets larger it becomes increasingly difficult to satisfy both parts of the rule with the same switch. This is an ideal situation for a remote switch. The solenoid is beside the battery, the operating switch is in a readily accessible location
Another advantage of remote switches is because high-amperage battery cables are so thick, heavy, and expensive that running them all over the place to accommodate a switch becomes a costly exercise. An RBS allows you to keep those heavy cables short (running directly between the battery and the motor) while controlling the connection from a small, convenient switch at your helm or dashboard. This reduces voltage drop and simplifies your wiring layout.
