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 48 mile-long waterway allows ships to pass between the Atlantic Ocean and the Pacific Ocean. Before the canal was built ships would have to travel around Cape Horn, the southern tip of South America. That would be a voyage of an additional 8000 miles! It takes a cruise ship about 12 hours to traverse the canal. When you cruise through the canal three sets of locks of the two-lane canal work as water elevators that lift the ships to the level of Gatun Lake, 85 feet above sea level, and later lower them again to sea level on the other side of the Isthmus of Panama.
