Anyway, like BCJ said, smaller boats are just fine for the grand. The main question here is whether it will hold all your beer. If you have passengers, I would consider a bigger boat for comfort and capacity. Ether way, I wouldn't buy a boat just for one trip. Perhaps you should think about your future needs/ wants.
Navajo's are good, solid boats, but its been so long since they made them you would have to find one that's been tucked away in somebody's garage for decades if you want something nice. They're heavy. Lots of extra rubber on the bottom. Look at the valve boots for cracking/leaks. Make sure the rubber on the top of the raft is pliable and not chalky. I took my old Navajo to the dump last year because the rubber was just done.
