Rowbot #310 is one of the multitude of robots that is attached to a boat, known as a Rowbots. Their primary purpose is to transport people across the ocean from the Barrens to the Glen and vice versa. They have a built-in navigation circuits which allows them to calculate the path and shortest route between the ports in the Barrens and the Glen. They also have the ability to trace materials from their source locations, which in turn activates their backup tracking system. This backup system is used when Niko presents the amber that Silver gave to them to the Rowbot. They are powered by the electromagnetic field of the generator in the Barrens.
