Have done 2 seasons in Bahamas and embarking on 3rd in a
boat that draws 7'6" no problems at all just read the
charts and go where you can. There are at least a 1000
anchorages that you can which is enough for most peoples life times!
Your
mast and the US coast is the issue, we have 66' mast and our standard
route is:
Hampton - Cape Lookout Bight - Wrightsville Beach - Charleston - St Marys -
Lake Worth -
Bimini. This means anchoring and no marinas/bridges.
You would also have an option at Port Royal, Canaveral (marina) and St Augustine we just haven't bothered. I may have missed others but that
route means no
passage more than 1 night at sea and gets you south quickly.
