Bingo! Benn nailed it.
Here's a recent photo and comment from a sailboat delivery I did this spring from Ft. Lauderdale, FL to Barnegat, NJ. Find the strongest currents by the water temps and ride them north.
"Hello Gulf Stream. Water temps in ICW and along the Florida coast were in the lower 70's. Once the strongest part of the stream we saw water temps of 86 F plus. I was on watch when we rounded Hatteras and left the stream. Water temps went from 81 to 56 F in 3 miles."
