Which then raises the question of whether it really has a parallel. If a world routinely had wizards who witched the wind into the sails, how would that affect the building of ships? Assume stagnation and pick a name for something like the era?
Especially given that the ships I am working with do not sail extremely far. (It's magic. I read a comment about bad world-building, namely putting pirate strongholds far, far, far away from any possible trade routes. So I figured out a way where that would not matter. 0:)
And all this while still wrestling with the notion of whether to open the story that early. . . .
