Although this word was made up in order to be a contender for the longest word in English, it can be broken down into smaller chunks in order to understand it.
Anti- means that you are against something; monopoly means the exclusive control over something; geographic is related to geography; and the remaining part has to do with nationalism.
So this word means something like 'a nationalistic feeling of being against geographic monopoly,' but you can see that it doesn't have much sense.
Between lines 9-19 we can see that the boatswain has little tolerance for passengers and wants them to be away from their place of work. This is evident when he continues to send passengers back to their cabins and further states that that ship does not carry anyone he loves more than himself.
We can deduce that Alonso, Antonio and Gonzalo are men of great courage, since they do not repress themselves with the boatswain's attitudes, do not fear death by drowning (although they would rather die on dry land) and are very loyal to their king, since they decide continue with him in that moment of eminent death.
