Lt Cdr Aishwarya Boddapati recounts her extraordinary journey circumnavigating the globe on INS Tarini with an all-women crew of six. Her talk, part of Navika Sagar Parikrama, details the extreme challenges of self-sufficiency at sea, from repairs to charting, while battling rough weather, strong winds, and sub-zero temperatures in the unexplored South Oceans.
