Have done both the doubloon and Captain Nautica's. Enjoyed both for different reasons. They both go to Turtle Cove but Captain Nautica's also takes you to Honeymoon Beach at St John due to the fact that you are traveling about 40mph in a very fast boat. The doubloon only goes to Turtle Cove and is a wonderful experience but just at a slower pace. If you and your boys have a need for speed then Captain Nautica's is the way to go.....if you just want to rest and relax as you come and go to the island then the Doubloon is the way to go. Both crews are fabulous and your trip no matter which one you choose will be memorable. Have fun!!!!
