We made a smooth crossing over Bonaparte Gulf, where glass conditions allowed us to spot large sea snakes rising for air at the surface. We then sailed into Darwin Harbour for a technical stop.

Darwin Harbour was discovered by the crew of HMS Beagle during their exploration of the north coast of Australia in the 1840s. After viewing the large laterite chalky cliffs on the entrance to the vast harbour, the maritime team reflected on their former naturalist friend and shipmate Charles Darwin and his fascination with geology.
