An amphibious jeep had already (1954-56) driven from the
Arctic Circle to Tierra del Fuego but it used its amphibious
capabilities to sail (drive?) around the Darien Gap!
- Helen and Frank Schreider, `La Tortuga', 1957.
The Schreiders subsequently took an amphibious jeep around
the islands of Indonesia, `The Drums of Tonkin', 1963.
Another amphibious jeep, `Half-Safe' (surely an overstatement),
was sailed across the Atlantic Ocean by Ben and Elinore Carlin in 1950.
It then went on to complete a circumnavigation of the world,
finishing in 1958.
