Oceans Seven

It includes the North Channel, the Cook Strait, the Molokaʻi Channel, the English Channel, the Catalina Channel, the Tsugaru Strait and the Strait of Gibraltar.

Alternative definitions

An alternative definition of the Oceans Seven is one channel from each of the seven continents, just as the Seven Summits refers to the highest summit on each of the seven continents. For this definition, the list would include a South American channel and a swim in Antarctica. For example, Lynne Cox has swum channels in 6 continents and swam for 25 minutes in Antarctica.
