And a draft of less than 5 feet is recommended, but that is for the main channels I would think. I know that some of the rivers and marsh areas would require alot less, and for gunkholing I'd like a cat with just a few inches, not more than 18" and beachable for those mud banks.
You won't be sailing in much of the Great Loop as I understand it, I'm thinking 70/30, 70% motoring. And there is a stretch of the lower Mississippi
where you'll need a 400 mile range for fuel
, otherwise it will be trucked to you....$$$$. Guess that would be up river, cause you can float at a good clip heading down in some places, right along with the houses, refrigerators, propane tanks
and maybe a car or two.
