Serge Testa is an Australian yachtsman who holds the world record for the circumnavigation in the smallest boat, completing the voyage in 1987. His 11-foot-10-inch (3.61 m) boat, the Acrohc Australis, was designed so that all controls could be operated from inside enabling him to close the hatch in foul weather. The boat is currently on display at the Queensland Maritime Museum in South Bank.
