Herald of the Morning was one of the few clipper ships with a passage to San Francisco in less than 100 days.

Construction
Herald of the Morning was designed by Samuel Hartt Pook. 'Her lines were sharp, approaching those of an actual clipper, yet she could carry in dead weight close to 1600 tons."
The Mauritius Commercial Gazeteer described the bow of Herald of the Morning as "so sharp as to take the form of a razor, the keel forming the edge; there are no rails at the bow, which is quite unencumbered".
An 1854 Boston Daily Atlas writer was impressed by the beauty of her accommodations, and described the ship's overall appearance thus: "Her stern is oval in outline, and is finely ornamented with gilded carved work. She is sheathed with yellow metal, and is painted black outside; inside she is white, and the waterways blue, and her rack rail is covered with yellow metal fore and aft."

Named after ancient goddess
The name Herald of the Morning refers to Eos (Greek) or Aurora (Roman) the Goddess of Dawn. Her figurehead was a "full figure of Aurora ... placed to correspond with the inclination of the cutwater."

Voyages
Herald of the Morning had a reputation for speed. She made 18 passages around Cape Horn during the 20 years she was under the U.S. flag, and two homeward trips around the Cape of Good Hope.

Struck by a sperm whale
Herald of the Morning was struck by a very large sperm whale off Cape Horn in 1859. The whale sustained severe injuries. “The ship lost part of her stem, and the pumps had to be kept going until her arrival at destination.”
