I don't worry about the water on board but we are going Cozumel and Belize and I'm not planning on eating or drinking anything. We are going to take some light snacks and some bottled water. I haven't decided yet whether to bring it or buy it or both since their are 6 of us buying bottle water for two 7 hour trips could be costly.
