Fastest ocean liner

The fastest ocean liner is a passenger ship designed for rapid transoceanic travel, primarily during the early to mid-20th century. Its speed is achieved through powerful engines, streamlined hull design, and efficient engineering, allowing it to reach high speeds—sometimes over 30 knots (about 35 miles per hour). This combination of technology and design reduces travel time across oceans like the Atlantic or North Atlantic routes. Examples include the RMS Queen Mary and SS United States, which set speed records. Such ships prioritized speed to serve urgent or prestigious passenger and mail routes before the dominance of air travel.
