Exploring the Cabin Class revolution and its six greatest vessels, a trio of competitive pairs In the wake of the U.S. government s immigration restrictions introduced following World War I, the classes of accommodation on the North Atlantic changed dramatically, triggering the rapid rise of the Tourist and Cabin grades. These proved extremely popular, offering a high standard of service for a relatively modest fare, undercutting the established First Class trade and acting as a catalyst for the leading shipping lines to invest in modern, quality tonnage specifically for this new class, even at the expense of planned giant liners. Six outstanding ships emerged, three competitive pairs: the "Lafayette "and "Champlain "representing France, "Britannic" and" Georgic" flying the Red Ensign, and "Manhattan "and "Washington," the most advanced American-built liners up to that time."
