This is an old technique that appears in Beowulf and other classic texts that came from oral traditions: it is cataloging. It is often used to list treasured collected or in this case to show expansiveness of the fleet (and memory of the teller, perhaps?)

Think about 10 year olds talking about all the different candies they are going to devour on Halloween night to get a sense of how it is meant to resonate with a crowd.

If the only way you could hear about Napoleon's battles was having a guy recount them to you in verse, I bet it would sound pretty impressive when he started listing off all the regiments present for a battle, their commanders and deployments. There's a sense of scale to it, that probably isn't captured by just saying "such and such number of ships and such and such number of soldiers".
