The greater breadth of the American ships in proportion to their length meant power to carry canvas and increased buoyancy which enabled them, with their sharper ends, to be driven in strong gales and heavy seas at much greater speed than the British clippers.

The latter were seldom of more than one thousand tons' register and combined in a superlative degree the good qualities of merchant ships.
* "The Clipper Ship Era." N.Y., 1910.
It was the California trade, brief and crowded and fevered, which saw the roaring days of the Yankee clipper and which was familiar with racing surpassing in thrill and intensity that of the packet ships of the Western Ocean.

In 1851, for instance, the Raven, Sea Witch, and Typhoon sailed for San Francisco within the same week.

They crossed the Equator a day apart and stood away to the southward for three thousand miles of the southeast trades and the piping westerly winds which prevailed farther south.

At fifty degrees south latitude the Raven and the Sea Witch were abeam of each other with the Typhoon only two days astern.
Now they stripped for the tussle to windward around Cape Horn, sending down studdingsail booms and skysail yards, making all secure with extra lashings, plunging into the incessant head seas of the desolate ocean, fighting it out tack for tack, reefing topsails and shaking them out again, the vigilant commanders going below only to change their clothes, the exhausted seamen stubbornly, heroically handling with frozen, bleeding fingers the icy sheets and canvas.
