[Pirates of the Caribbean] At worlds End. Why was the final battle a 1v1 despite the vast amounts of ships on both sides?

It always confuses me as I’ve tried going scene by scene to the end to find out why it’s only one on one. It seems super lame too since after this huge inspiration speech it’s just two ships instead of the whole navy vs the pirates.

It's basically like combat by champion, but with ships instead of single people. They let their best ships fight, and the side whose ships win get the victory of the whole combat. That greatly reduces the price in ships and lives.
