Narrowboat kitchen pic from NCM carpentery. I haven't seen a lot of boat kitchens that look like house kitchens, but this one does in all the best ways. I'm not sure about the counter drain board though (seems grotty and impractical).
If I opened the ship up, it would be closer to this. It would be 15 feet wide, though, so it would be a lot wider than boat in this picture. Really nice, but could it still be a B&B as well? Would it work to have just half the ship open plan?
