Hi we chartered from Sail Caribe last May and had a great time, you will not be disapointed. We loosely followed their sample itinerary.
Our faves were
Rosario Beach on
Culebra, free
mooring balls great snorkeling and a trail over to flamenco. Melones beach is a short ride to swim with the turtles.
Culebrita, beautiful little anchorage, great trails, and the view from the lighthouse is amazing. Be forewarned though it is busy on the weekends.
Esperanza on Vieques was a nice stop. The bio bay was a bit disappointing but the wild horses made up for it.
The Spanish Virgins are pretty
remote. No
marinas or anything once you leave Fajardo. The only restaurants are in the towns, DeweyTown on
Culebra, or Esperanza on Vieques.
Hope this helps pm me if you need any more info
