President Pranab Mukherjee on Saturday (April 6) accorded a warm welcome to Indian Navy's Lt Cdr Abhilash Tomy who became the first Indian to circumnavigate the globe, solo and non-stop, over a 150-day voyage. "To sustain a long voyage of over 150 days at sea, solo, non-stop, unassisted and sailing through some of the most treacherous oceans of the world, is a remarkable feat."
