Here is an example of a cruise that would set sail from Miami Beach and would be expected to end up in the Virgin Islands in about 11 days. The total trip distance is 2069 nautical miles.
By boat it would take 258.625 hours (10.77 days) at 8 knots, by car 45.97 hours (1.9 days) and by glider 20690 hours (862 days).
Here is an example of the Florida coast that has a sea temperature map overlay-ed. You can see the evidence of the gulf stream in the bottom right of the picture. The overlay was taken on September 28th.
