FL to the Caymans - which route?
Oh golly, 3 weeks isn''t even close to the time I''m afraid you''ll need. Don''t forget you''ll occasionally need to accommodate frontal passages, at the very least during your Bahamas leg and again when striking out from either Isla Mujeres or rounding Cabo San Antonio and heading back to Florida. Discounting side treks, I make the approximate run from West Palm via the Windward Passage and subsequently via the Yucatan Straits back to Key West at 1800 NM or so; and you''d need to add some add''l distance from your departure point? Plus of course, making the effort doesn''t include the add''l time it takes to make it worthwhile.
