First powered Atlantic crossing by ship

The earliest crossing of the Atlantic by a power vessel, as opposed to an auxiliary-engined sailing ship, was a 22-day voyage begun in April 1827, from Rotterdam, Netherlands, to the West Indies, by the Curaçao. She was a 38.7 m (127 ft) wooden paddle boat of 445 tonnes (981,000 lb), built as the Calpe in Dover, Kent in 1826 and purchased by the Dutch Government for a West Indian mail service.
