Indian Naval Sailing Vessel Tarini, which is undertaking a global circumnavigation expedition christened Navika Sagar Parikrama II, arrived at its first port of call in Fremantle, Australia, on Saturday, officials said.

The vessel reached Australia after completing a 39-day voyage.

The expedition was flagged off from Goa by Adm Dinesh K Tripathi, Chief of the Naval Staff on Oct 2.

The vessel has covered a distance of 4900 nm from Goa, crossing the Equator on 16 Oct 24 and the Tropic of Capricorn on 27 Oct 24.

"During this 38-day non-stop voyage, the Indian Navy duo of Lt Cdr Dilna K and Lt Cdr Roopa A encountered a range of weather conditions from calm to severe, facing winds up to 40 knots and sea state of 6," read a government statement.

"Throughout the journey, the crew remained in good health and in high spirits, demonstrating resilience in the face of extreme conditions," the statement said.

The progress of the expedition has been closely followed by the CNS, receiving daily updates.

On the eve of Diwali, while the vessel was at sea, the CNS interacted with the crew and found them fully motivated and dedicated to their mission.
