Mark Sinclair has always been passionate about sailing and the sea. In 1968, at the age of 10, he started sailing, at the time when Sir Robin Knox-Johnston departed to become the first to complete a non-stop solo circumnavigation. In 1984, Mark completed two solo crossings of the Tasman Sea and gained his Yacht Master Ocean Certificate. Before entering the GGR, when on leave from work, Mark typically sailed his S&S 41 Starwave single-handed around remote areas of Australia. When Mark found out about the 2018 GGR, he applied immediately, sold Starwave and deferred his plans to compete in the 2018 single-handed trans-Tasman race; Mark purchased Coconut, a Lello 34 class yacht, for the GGR.
Mark’s professional background includes hydrographic surveying of remote areas in ships, small boats and aircraft. He served 20-years in the Royal Australian Navy, commanding three ships and navigating four, at the time when celestial navigation by sextant was still the primary means of offshore navigation. He retired from the RAN as a Commander in 1996. Mark currently works as the Director of Fugro’s Hydrographic Services in Asia-Pacific and conducts hydrographic surveys worldwide. Mark is married with three children.
