The question "how do cruise ships move sideways" refers to the ability of these massive vessels to maneuver in tight spaces and navigate complex waterways. One notable example is the "crab walk" technique, where ships use their thrusters to move sideways without turning their hulls.
This maneuverability is crucial for cruise ships to dock in crowded ports and navigate narrow channels. It also enables them to perform precision turns and maintain stability in strong currents. The development of advanced thruster systems has been a key historical factor in enhancing the sideways movement capabilities of cruise ships.
