There are 2 engines and if you put one in forward and the opposite one in reverse, the boat will pivot. With the aid of a bow thruster that you can clearly see working , the boat can move sideways. an experienced captain can move a twin engine sideways with out a bow thruster. Cruise ships are another story! I've maneuvered and docked yachts up to 140 ft with no bow thrusters. You let the wind do a lot of the work.
