By 1850, this journey was halved. For instance the clipper ship Oriental was able to sail from Hong Kong to London in 97 days that year. The absolute one day distance record made by a clipper involved 436 nautical miles. Clipper ships were fast but no specific rig type was standard. By 1845, the term was used in conjunction with a name indicating the cargo carried or area served by a fast-sailing vessel and a specific rig type was usually indicated.
The Cutty Sark was also a very fast ship. She once sailed 2,163 nautical miles in six days, for an average speed of just over 15 knots. Nevertheless, the Sovereign of the Seas, the Cutty Sark and other fast sailing ships did not average such speeds. The Cutty Sark set a record for a passage from Plymouth to Sydney of 72 days, when a fast passage was considered to be anything around 100 days.
