I make
Bahamas several times with my 6.6
draft, with carefull planing and caution you dont have problems, never touch the bottom in Bahamas , with a Cata the options to navigate shallow banks and found
remote shallow
anchorages increase, if the Keys and Bahamas are going to be your sailing areas goo for the Cata if draft is a worry for you, between 5 and 6 ft draft are fine for Bahamas , im not sure in the Keys, Bahamas are awesome, enjoy!!!
