You're going to find this very difficult to do, as transatlantic cruises are rare, very expensive and only use a few ports. Cruises like this tend to be luxury, and much more expensive than a flight. You can see journeys currently scheduled here:

The only ships listed this time of year leave from the northeastern US and go to the UK. You would need to first get to NYC from Florida. From the UK, you would have to travel by various ferries, trains and busses to get where you want to go. It would take 10-15 days (including travel within the US and Europe if you don't fly), and likely cost thousands of dollars each way.
