Ft. Myers, FL to Charleston, SC - Best route

[autolake]

I was just wondering if I could get some help. I am fairly new to boating.

I am moving a 1993 630 Sea Ray Super Sun Sport with twin MTU 1100. It has a 5 foot draft. I am not currently at the boat and don't have my chart plotter.

Also, does anybody have any idea what the mileage would be and my approximate fuel consumption running at approximately 15 knots.

It has an 800 gallon fuel tank. Where would I be best off to stop off for fuel. I have heard that if I go out to the gulfstream my consumption would be lower, despite the additional distance.

How long should I allow for the move?

Your help is appreciated
