OK, I’m sure the answer to this question is a resounding *NO!**. I’m sure the distances, cost, and potential danger all make the idea I’m about to discuss impractical. But here it is:
Is there a New Orleans-to-Tampa ferry? If so, how long does it take and how much does it cost?
According to my digital street atlas map this appears to be a 450-500 +/- mile open ocean voyage. Something which is beyond what a “ferry” normally traverses.
The road trip along the coast is relatively straightforward and only appears to be approx 40% longer (as the crow flies) than the water equivalent. Using a ferry vs the roads in this context for moving people (assumedly your question) wouldn’t be impractical, it would be insane.
There may be special, large scale objects that are too large for highway overpasses that would need to go by water but I can’t imagine any other reason for a ferry vs a car/bus in this context.
