Usually two or three times a year we put the boats in and go up river 8 or 10 miles and set up camp and there is usually six or seven adults and 10 to 12 kids. I have seen as many as 8 boats up there and it lasts about 4 or 5 days. We always go in heavy and unload everything and set up camp then spend the rest of the time fishing or swimming, and we all take turns cooking.
Weight is important enough, sometimes we have to make two trips to get all the people and gear in there, but this year I bought a new boat :B and its big enough to handle it.
I am actually thinking about buying a chest type tool box for a truck and mounting it in the front of the boat just behind the casting deck. That would be plenty big enough to hold everything we need plus some life jackets too and I could lock it and keep it secure when its out of sight.
