Hydroptère
The Hydroptère (or L'Hydroptère in French) is a hydrofoil built as a trimaran . From 2007 to 2012 she held the official world speed record for sailing over a nautical mile and has improved this record several times. The yacht is 18.28 meters long and 24.0 meters wide, has a displacement of 4.7 tons, a movable water ballast of 800 liters and a sail area of 400 m². It was designed by the French windsurfer and sailor Alain Thébault , based on a project by the French ocean sailor Eric Tabarly , and further developed in cooperation with the Swiss Federal Institute of Technology in Lausanne .
On February 9, 2005, an average speed of 33.3 knots (61.67 km / h) was reached when crossing the English Channel and on April 4, 2007, the prestigious world record for sail-powered watercraft was 41.69 knots (72.21 km / h) Temporarily brought back over a nautical mile by windsurfers. On this trip, a new record was set over the 500-meter distance with 44.5 knots (82.41 km / h).
In December 2008 the ship capsized in a promising attempt to record a record at 55 knots (102 km / h). Some crew members were slightly injured and the boat was seriously damaged. A top speed of 61 knots (113 km / h) was briefly reached during this journey.
In 2009, the Hydroptère set the records for the first time over both short distances over 50 knots: 51.36 knots (95.22 km / h) over 500 meters and 50.17 knots (92.91 km / h) over the nautical mile. At a wind speed of only 30 knots, the 100 km / h limit was briefly exceeded. The fact that both records were held at the same time was rarely the case before. What is more remarkable, however, is that they are almost identical and thus the potential is shown to sail much longer distances with consistently high speed. In the times of record surfers, it took a lot of luck and the best wind and wave conditions to drive through the measuring section without accidents. The speed record of one nautical mile was broken in November 2012 by Paul Larsen on the Vestas Sailrocket 2.
Unlike the previous record holders Crossbow 1 and 2, Yellow Pages Endeavor and the various windsurfers and kitesurfers, Hydroptère was built as a basically ocean-going yacht that can sail all courses. For example, it has a built-in engine, a "habitable" cabin and z. B. permanently installed position lights . In contrast to its predecessors, it is not specially designed for record hunts over short distances on exactly one course to the wind, but can reach exceptional speeds on all courses as soon as it only hovers on its wings and is sailed "quite normally" by its crew and maneuvered. A consortium led by Alain Thébault planned to sail around the world in less than 40 days with the experience from the Hydroptère with a 30-meter-long wing trimaran. This record attempt could no longer be tackled after the yacht had to be sold due to financial problems after a failed record attempt on the San Francisco to Hawaii route .
