10 of us are taking a cruise in December and I have found a catamaran we can go on privately for around the same price as going on a bigger catamaran with other people. If we don't get lunch, then it is much cheaper than going on the bigger boat. Anyone been on this boat?

For $25 extra for lunch and drinks, i think we can save some cash and bring our own. Can you bring your own alcohol if you charter a boat?
