Holy Batman!
It may looks very fictional, but it is actually powered by Merc Cruiser Chevrolet V-6 engines which allows Batboat to achieve the speed up to 45 miles per hour. The interior had many props and gadgets over the stern drive, and they also constructed a fake jet nozzle and water squirter to give the appearance of a nuclear boat motor.
Hot Wheels is one of the licensees to produce Batman's vehicles and they also have released a model to commemorate the 1966 model Batboat. Why 1966? This is because in 1966, a Batman film has been published and this model used by Batman in the film.
note to myself: never put diecast boat into the water.. It will sink!
