Water speed record
The world speed record on water is similar to that found in the country for motorized water vehicles in different classes and types. The Canonizing / sanctioning organization here is the UIM ( Union Internationale Motonautique ) in Monaco, the counterpart to the World Sailing Speed Record Council for sail -powered watercraft.
To record the U.I.M. set up in the category of speed (maximum speed ), two tests must be taken in the opposite direction within one hour. In each case, the time taken to travel one kilometer from a flying or a flying mile. From the measured time, the speed of the run is calculated from the average of two runs, then the record. To be recognized as a new record, the speed must be at least a factor of 1.003 is higher than the previous record. Only the records with a run sail -powered watercraft are determined, as there is a reciprocal course would not be due to the dependence on wind direction and feathering usually fast enough.
Other categories for U.I.M. records are:
- Course record: Depending on the class are a certain number of laps on a course of up to 6 nautical miles to go
- Duration Result: It is one of the average speed, which is achieved within 1, 2, 3, 4, 6, 9, 12 or 24 hours. Refueling and driver changes are allowed.
- Race Records: What counts is the speed that is achieved during a competition with several boats over 3, 5, 10, or 15 nautical miles.
With the absolute speed record, there are no rules for boat and motor, otherwise the rules for each boat class apply.
- Fastest driver of a motor boat is Ken Warby from Australia. He drove on 8 October 1978, his jet-powered Spirit of Australia 317.60 mph (that is 511.13 km / h ).
- Fastest driver of a propeller-driven boat is the American Dave Villwock. He went on 13 March 2004 with the "Miss Budweiser " 220.55 mph (that is 354.86 km / h ) on Lake Oroville.
- The Vestas Sail Rocket 2 posted on November 18, 2012, an average speed of 55.32 knots (that is 102.45 km / h ) over a mile, and on 24 November of 65.45 kn ( 121.12 km / h ) about 500 m each world records for the fastest sail -powered watercraft.
Development of absolute U.I.M. cup record
Development of record for propeller-driven boats
The boat Slo -Mo - Shun IV was the last driven by a propeller boat that held the absolute speed record on water. Since then, this record has evolved as follows:
