I just checked with a Fountain guro you will probably be spending 4200 - 5000 in fuel to get down there.
The 37t came up by water from Miami to Annapolis a month or so ago and total run time between 2.5 days was 24 hrs with a stop in Cape Canaveral and Georgetown SC
It would we way cheaper to put the boat on a truck and ship her down by far. Less wear and tear on the boat and no unexpected breakdowns in between.
If you need help with finding a transporter let me know, I have a few that can help out that make trips down regularly
Best of the best with the travels
thanks for all the input
