Dunno your scheduled departure..... BUT this time of year I would not rhumb line sail anywhere in the Gulf or Caribbean
if it were going to put me more than 24 hours from a hurricane
hole! Just sayin'! I have made the trip to St Thomas in August once.... I'll never do it again.
But if you do go and have the time, there is a lot to see on the West Coast
. Personally, I would go from Mobile to Cedar Key, then Tarpon Springs, Tampa Bay, Sarasota
, Boca Grande, Ft Myers Beach, Marco Island, Shark River, Marathon (inside), then Key West
. If you still have the time, cruise
the Keys to Biscayne Bay, and hop to Bimini
. Then either (again time permitting) North to Walker's via Grand Bahama, work your way down the Abacos and island hop to T&C, D.R., Puerto Rico
then the Virgins.
I spent 6 weeks from KW to St Thomas on that route and still bypassed a lot of cool stuff.
