Doing a bareboat with SailCaribe in Dec 6 on a cat with only a 79 gal water tank. We have 6 crew and 9 days on board. Our intention was a tour through Culebra/Culebrita then to Vieques but we're not finding much for refilling the water tanks on that itinerary.

What would you folks recommend for an itinerary with at least one place to stop along the way? 79 gallons just seems REALLY small when our last BVI trip had 8 people, 7 days and we went through about 300 gallons.

Thanks for any suggestions.
