 The other entrance is Schooner Channel, formerly Schooner Passage, on the east side of that island.The Fox Islands, which lie in its entrance, Bramham Island and the channel itself, plus Slingsby Rock and Slingsby Point, are named in association with Bramham Park, the Yorkshire home of George Lane-Fox.Through the Slingsby Channel flows the world's strongest current, the Nakwakto Rapids, that has been measured at speeds up to 18.4 miles per hour.
