\n R/V Falkor is a 82.9 m (272 ft) LOA ship originally built in 1981 in Lübeck, Germany as a fishery protection vessel.

\n

\n The ship went through an extensive refit from 2009 to early 2012, \nconverting the ship to an oceanographic research vessel. Cruising range \nand endurance are estimated at 8,000 nautical miles and 28 days of \nsteaming (fuel-limited) at a cruising speed of 12 knots.
