RV Le Suroît is a French research vessel operated by IFREMER.[3] In 1985, it was involved in the successful Franco-American expedition to find the wreck of the RMS Titanic.[4][5]
Since being refurbished in 1999, the vessel is able to undertake bathymetric and seismic research, as well as coring, dredging, and trawling tasks.[3]
History[edit]

The vessel was commissioned and built in 1975 by Ateliers et Chantiers de la Manche in Dieppe, Seine-Maritime.[6] In 1985, the ship was equipped with the new System Acoustique Remorqué (SAR) sonar device. In early summer, the vessel undertook a 10-day sonar mission[7] in an attempt to find the wreckage of RMS Titanic.[4] Aboard Le Suroît on this mission was Robert Ballard. Le Suroît was able to rule out large sections of a pre-determined 150-square-mile (390 km2) search area – between 26 July and 6 August, 80% of the area had been searched.[8] It later transpired that on one of its first passes, Le Suroît had come within only 3,300 feet (1,000 m) of Titanic.[9] The mission ended on 6 August,[5] after which RV Knorr travelled from the Azores to concentrate on more specific areas using different strategies.[4]
In October 2011, the vessel was on assignment in Crete[10] before travelling to La Seyne-sur-Mer in December.[1]
Facilities and equipment[edit]
The vessel is equipped with a range of devices. The computers run IFREMER's CARAIBES mapping software.[2] The coring cable is 8 kilometres (5.0 mi) long and is made of Kevlar. It has a safe working load (SWL) of 8 tons.[2] The ship also has a 6-kilometre (3.7 mi) steel winch, with an SWL of 2.1 tons. The average cruising speed, and the speed at which surveying is undertaken, is approximately 10 knots (19 km/h; 12 mph).[11]
