I know you are talking about real boats, but I just bought a new kayak (sold my first one) because the new one has a seat for Sophie. She wasn't real crazy about the first one, but the new one has much more room. Last Sunday we tried it for the first time, and although she wasn't over joyed by the new seat, she seemed to like sitting in the hull which has so much more room for her. It was really fun, and I hope to take her out on the lake this summer after work.
