Could Brazil's rivers and forests have supported an earlier shipbuilding industry?

With earlier investment, could Brazil's forests and rivers have made it a good shipbuilding centre?

Yes. Rivers offered a way to move timber from the interior, although iron supplies and a working construction industry would still be needed.

Brazil's geography offered useful timber transport through rivers flowing out of the forested interior. Earlier investment could therefore have supported a regular supply of wood and an organized construction industry. Shipbuilders would still need iron and other materials alongside timber. Bombay and Goa provide comparisons for what British and Portuguese shipbuilding could achieve overseas. Bombay's teak warships were especially highly regarded by the Royal Navy, reinforcing the point that Brazil's missed opportunity concerned timing and infrastructure rather than a simple shortage of suitable resources.
