The Port of Mumbai is situated almost midway (Latitude 18o 54’ N, Longitude
72o 49’ E) on the West coast of India and is gifted with a natural deep water Harbour of about 400 square kilometres protected by the mainland of Konkan on its East and Island of Mumbai on its West. The deep waters in the Harbour provide ample shelter for shipping throughout the year. The approaches to the Harbour are well lighted, with the Prongs Lighthouse to the North, visible 27 kilometres and the Kennery Light House to the south visible 29 kms. The entrance of the Harbour which has approaches from the South-west is between Prongs Reef and the Thull Reef lying off the mainland to the South-east, a distance of about 9 kilometres.
The main navigational Harbour Channel is, for the great part, a natural deep-water fairway. The channel has been deepened to 11 metres. With a mean high water neap tide of 3.3 metres, the channel is adequate to meet the requirement of a large number of cargo vessels, passenger ships and deep drafted tankers. With good lighting arrangements navigation is allowed at the port round the clock.
