On 28 September 1985, a group of 10 sappers led by Colonel T.P.S. Chowdhury set off on a 55,000 km odyssey in an 11.2 m (37 ft) long, 10.5 tonne, fibre-glass yacht, Trishna. They sailed from Mumbai, Maharashtra, to Malé, Mauritius, to St. Helena Island. Crossing the Equator for the second time, they sailed into the Port of Belem in Brazil, then through the Panama Canal towards the Galapagos Islands, touched the Polynesian islands, Bali, and reached Mumbai, Maharashtra, on 10 January 1987.
