How do I get boats as a primitive nation in EU4?

I have been testing multiple times as the Inca's, and I cannot seem to get boats, please help.


You get access to ships once you reform / westernize.

Until then you are not able to build any. The idea is that a "boat" represents an equivalent of a european ship-of-the-line. Tribal nations didn't have anything comparable to them, no matter how entertaining it would be to see a fleet of wooden dinghies go up against a 36-cannon broadside.
