Ben Carlin in 1958 became the one and only person to circumnavigate the world in an amphibious vehicle. He and his wife Elinor started the trip in the last part of 1947 aboard the Half-Safe, a former military amphibious vehicle. After several tries, they reached Morocco in 1951. Elinor flew to the United States, and Carlin found other mates to continue his voyage. Pausing to earn funds and repair the vehicle, he returned to Montreal in 1958. After Carlin’s death, the Half-Safe was deeded to his school in Australia, the Guildford Grammar School.
