Boats like that are usually custom built for the park, often by park staff, often without too much knowlege of boats. When they come to the end of their useful life, they were often sold on. Today they might find their way on to auction sites. It becomes a matter of dumb luck finding one. But there are lots of kits on the market covering a huge range of types. However, most will be properly proportioned and based on something real.
