If I wanted to get a job aboard a cruise ship, how would I do that exactly?

I think it would be cool to get a job on a cruise ship. I live in NJ, so it isn’t like there are cruise ships passing me all the time with signs posted “now hiring”. I looked online for a little bit, and I found a website cruiselinejob.com, but that doesn’t seem like a good start or a lot of help.

Any tips or pointers on what I should do to get a job on a cruise ship. And I’m saying I would do pretty much any job that I would be qualified for, so that should widen my possibilities.
