I enjoy good wine almost as much as anyone, but I tend to not drink it on the boat very much. Of all the beverages, wine tends to dehydrate me the most, something that can easily sneak up on you on the water. (ie, headache!) Also, most all wines will have varying degrees of sediment, that should normally stick to the dependent portion of the bottle when racked. A boat's motion will keep the sediment in solution, and quite possibly affect the quality of the drink. Many mass produced wines (some excellent) are filtered and don't have this issue. I make a lot of my own, and they don't travel well.
Mostly my personal experience and opinion, FWIW.
