Greetings, and WELCOME aboard lilyplove. Florida to and thru' the Caribbean seems a little ambitious for a six week cruise.
Six weeks might be an adequate time to cruise the Fla. Keys, or the Bahamian Abacos, or the Bahamian Northern Exumas; but not much more.

Sailing is slow, and if your not sailing 24hrs a day it becomes extremely slow. If you buy the boat in Florida then 6 weeks in the Bahamas will be a treat. May, or June would be better. July becomes a bit IFFY with serious weather.....HURRICANES......BEST WISHES, and enjoy
