Frederick Benjamin “Ben” Carlin (27 July 1912 – 7 March 1981) was an Australian mining engineer, soldier, and adventurer who was the first person to circumnavigate the world in an amphibious vehicle.
Sparked by an idea he had had whilst in the military, Carlin proposed that he and his wife honeymoon by crossing the Atlantic Ocean in a modified Ford GPA (an amphibious version of the Ford GPW Jeep), which they named the Half-Safe. Beginning their trip in Montreal, Canada, the Carlins finally completed the transatlantic crossing in 1951, after unsuccessful attempts.
From there, they traveled to Europe, temporarily settling in Birmingham, England, to raise more money. They departed England in 1954, travelling overland through the Middle East before arriving in Calcutta. After a short fundraising trip to Australia, Carlin’s wife left to return to the United States. He resumed the journey with new partners, travelling through South-East Asia and the Far East to the northern tip of Japan, where he then sailed to Alaska. After an extended tour through the United States and Canada, he and Half-Safe finally returned to Montreal, having travelled over 17,000 kilometres (11,000 mi) by sea and 62,000 kilometres (39,000 mi) by land during a ten-year journey.
