Indian Ocean Shipbuilding Archive
Engineering, hydrodynamics, and maritime innovation across millennia
India pioneered stitched-plank shipbuilding — flexible, hydrodynamic, and ideal for monsoon seas.
Timber selection, resin waterproofing, rope engineering, and hull geometry.
Hull shapes optimized for stability, speed, and long-distance ocean travel.
Indian shipbuilding influenced Arabia, East Africa, and Southeast Asia.
A Maritime Engineering Civilization
Indian Ocean shipbuilding was a scientific and engineering discipline combining hydrodynamics, material science, ecology, and navigation. Indian shipwrights built vessels capable of crossing thousands of kilometers of open ocean, forming the backbone of the Indian Ocean knowledge network.
Ship Types
Major Indian Ocean Ship Types
Stitched-Plank Ships (India)
Planks stitched with coconut fiber; flexible hulls ideal for monsoon seas.
Dhows (Arabia)
Influenced by Indian hull geometry; used across Arabia and East Africa.
Patamar (Western India)
Large cargo vessels used for long-distance trade and knowledge exchange.
Catamarans (South India)
Indigenous multi-hull designs spread across the Indian Ocean world.
Outrigger Canoes (SE Asia)
Shared engineering principles with Indian multi-hull vessels.
Baghala & Boom Ships (Arabia/East Africa)
Hybrid designs influenced by Indian shipbuilding traditions.
Engineering & Hydrodynamics
