weber kettle...you can mount it to the sand in a jiffie!lol
not to be a smart-ass but hell at least you dont have to worry about the mess on-board and the kids are all around the heat,...and you cant beat the price of a lil'weber!
but if you do go with the boat bbq?...i'll take a dog on wheat with mustard only?..."UTAH"....make that ...two!
