In 1887, John Bartholomew's Gazetteer of the British Isles described Pentland Firth like this:
Pentland Firth, strait, between Caithness and the Orkney Islands, connecting the North Sea with the Atlantic Ocean; is 20 miles long and from 6½ to 8 miles broad; its navigation is rendered difficult and dangerous by the rapidity of the tidal current - from 6 to 12 miles an hour - and by dangerous eddies or whirlpools.
