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.
One travel day is allowed for each 400 miles of official distance of ordered travel. If the excess distance is 1 or more miles after dividing the total official distance by 400, one additional travel day is allowed. When the total official distance is 400 or fewer miles, only 1 day of travel time is allowed.
