The simulation shows a person (in black) standing at the left end of a 2.4-meter-long red boat. The person then moves to the right end of the boat - how far does the boat move? This depends on how the masses of the person and the boat compare. The circles in the water are not life preservers, but instead mark the horizontal positions of the center of mass of the person, the person-boat system, and the boat.
