Looks like the next boat (I think), the "Meridian Ace" is almost to the Panama Canal. I believe it's the next boat as someone in this thread was told by their dealership that their car was on it.
If it follows the same path as the LEO leader, it will hit Puerto Rico, then Jacksonville, then Baltimore, then RI, then Boston.
The LEO leader was in:
Panama on the 1st
Jacksonville on the 8th
Baltimore on the 12th
RI on the 15th
Boston on the 16th
These numbers are all approximate as I searched back in the thread to deduce them.
