A BBQ is a popular addition to pontoon and larger lake boats, but I've never seen one operating in/on any smaller fiberglass boat before. I've taken my little jug BBQ with me many times and cooked on a sandbar, but never close to the boat. Fire next to anything with a bilge sounds kinda scary. Now my pontoons have had mounts that hang the small propane BBQ on the rail, but those are all propane, or at least all the ones I've had or seen were. In addition, my toons have all been OB, so no bilge area. Houseboats I've seen with regular BBQ grills on their decks, but those craft have had kitchens to think of it, maybe they are safer?
