A few things to consider.
THE GULF STREAM
; it runs north at a considerable clip, making going south a bit tougher. There is a counter current
near shore, but then you've got to be on your toes; lots more traffic & things to hit (buoys, fishing
markers, breakwaters, etc).
I would not go out around Cape Hatteras; use the ICW, period; you'll have to power.
If you watch the weather closely, you can hop south behind fronts, taking advantage of northerlies & westerlies; taking a break in southerlies.
Hurricanes are not something to consider lightly. Watch the weather closely & try your best not to be where one is going to be. Finding a sheltered anchorage that is not over crowded with other boats (in other words, something that when it gets loose, will damage or sink your boat) is pretty hard these days.
To me a delivery
is just that; not a pleasure cruise
. I never let the boat get under 6 knots & run 24/7; push, push, push, but I hope you can be more relaxed than that.
