Coastal Shipping
Why moving cargo along India's own coastline by ship remains genuinely underused, despite being cheaper than road transport
Imagine cargo moving between two Indian coastal cities, Chennai to Kolkata for instance, and having a genuine choice between a truck driving the entire overland distance, facing traffic, tolls and road wear costs, or a ship sailing along the coast instead, a considerably cheaper option per tonne of cargo moved over long distances, yet coastal shipping has historically captured only a modest share of India's total domestic cargo movement compared to its cost advantage.
This underuse reflects several genuine structural factors, coastal shipping works best for bulk, non-time-sensitive cargo moving long distances between coastal points, exactly the opposite of the fast, flexible, door-to-door delivery road transport, covered under Logistics elsewhere on this site, naturally provides, meaning coastal shipping and road transport genuinely serve different cargo profiles rather than competing head-on for the same shipments.
The cabotage rules covered elsewhere on this site directly shape who can actually operate coastal shipping routes, historically reserving Indian coastal trade for Indian-flagged vessels specifically to protect and grow India's own domestic shipping fleet, a protection that also, depending on how strictly enforced, can limit the available vessel capacity actually serving coastal routes if Indian-flagged tonnage remains genuinely limited.
Growing coastal shipping's share of India's domestic cargo movement is an explicit Maritime India Vision 2030 target covered elsewhere on this site, precisely because shifting even a modest share of long-distance bulk cargo from road to coastal shipping would meaningfully reduce road congestion, fuel consumption and logistics costs simultaneously, exactly the kind of structural efficiency gain that requires coordinated port infrastructure, vessel availability and cabotage policy working together rather than any single reform alone.
