Meals are served in the dining area located on the main deck and are a combination of local Costa Rican, American and international cuisine.  Snacks are served throughout the day and tea/coffee and soft drinks are complimentary during your stay on board.

The large dive deck is located at the rear of the main deck and has individual gear storage and personal camera lockers for each diver, camera table and charging points, fresh water rinse tanks and showers.  Diving is from one of the three 24ft tenders which take up to 9 divers to different sites allowing for uncrowded and incredible diving. There is no need to load and unload your scuba equipment for each dive as your gear stays on the tender throughout the trip.
