paragraph_text: Shipbuilding industry
  
  Mughal India had a large shipbuilding industry, which was also largely centred in the Bengal province. Economic historian Indrajit Ray estimates the shipbuilding output of Bengal during the sixteenth and seventeenth centuries at 223,250 tons annually, compared with 23,061 tons produced in nineteen colonies in North America from 1769 to 1771. He also assesses ship repairing as very advanced in Bengal.
  
  An important innovation in shipbuilding was the introduction of a flushed deck design in Bengal rice ships, resulting in hulls that were stronger and less prone to leak than the structurally weak hulls of traditional European ships built with a stepped deck design. The British East India Company later duplicated the flushed deck and hull designs of Bengal rice ships in the 1760s, leading to significant improvements in seaworthiness and navigation for European ships during the Industrial Revolution.
