I have been across the Gulf Stream several times, always at night except for one time when I had to come back to the mainland on a small powerboat. There was no wind on that day. It was extremely spooky. There were no waves. There were swells, but they were not like ocean swells that go in a certain direction. These were very long, low, flat, lazy swells that seemed to be coming up from somewhere below and didn't seem to be going anywhere -- just heaving up and down. It was like the Stream was a living thing, like it was breathing. Very eerie sensation.
