In February 2000, the British oceanographic research vessel RRS Discovery, operating in the Atlantic Ocean over the Rockall Trough west of Scotland, encountered the largest waves ever recorded by scientific instruments in the open ocean, with a significant wave height of 29.1 metres (95 ft) and individual waves up to 18.5 metres (61 ft).

This was a scientific research vessel fitted with high-quality instruments. Subsequent analysis determined that under severe gale-force conditions with wind speeds averaging 21 metres per second (41 kn), a ship-borne wave recorder measured individual waves up to 29.1 m (95.5 ft) from crest to trough, and a maximum SWH of 18.5 m (60.7 ft).
