Who else thought the Boat Plan was a terrible idea?

Throughout the entire game I was thinking to myself "Finding a boat and heading out to sea is a terrible idea! Sure, you're away from the Walkers and the immediate danger but what about food and water!?" Sure you could fish for food, but how long would it take for scurvy to set in? or other lack-of-nutrition based diseases? The group might be able to bring food and water with them but it wouldn't be long before they ran out and had to return to shore to get more and I think it would take at least a whole day if not more just to find just a little food!

Kenny's plan was a short-term solution in my opinion, if the choice was presented to me then I would opt to stay on dry land with Clem instead of heading out to sea. What do you guys think?
