Indeed, it would be quite impossible for a nation that doesn't even have a coracle to turn out a caravel, through the apprentice system or through any other means. Translations of Portugues or Spanish ship-building instruction manuals would probably have helped the Aztecs learn to build ships, but realistically large scale shipbuilding required the sort of infrastructure and metal tools that the Aztecs lacked.
However, the Aztecs didn't just did indeed have books writen on paper and hide. See here.
