World water speed record is a matter of positional data

摘要

With a well-deserved and fearsome reputation as the most dangerous of all the speed records, the world water speed record has stood since 1978, making it also the most enduring speed record. It currently stands at 317.6mph and is held by Australian Ken Warby who built the boat Spirit of Australia in his backyard. A surprisingly low-tech affair, Spirit of Australia is made of wood and is powered by a jet engine. But no record stands forever, and Warby's mark is set to be challenged in the near future by a British boat called Quicksilver.
