Is it a boat? Is it a lawnmower? No, it's ... both. Sort of, anyway.

An intrepid amateur inventor has created an amphibious contraption out of a lawnmower and an old boat.

That's right, a riding lawnmower and a leaky old boat. Cue what the machine's creator calls a "shortcutter": a car that goes 6 mph on land ... and slightly faster in water.

The name of this contraption's creator is John Hinton, and he's 76 years old. Not bad for a man of a certain age, no? We'd love to be up to such antics when we're in our 70s.

As you'd expect from its low speed, Hinton calls it a "work in progress." He's still perfecting it in his hometown of Horsham, West Sussex, U.K., with his friend Laurie Mayhead. Thus far, he's spent $1,500 on the project.

Believe it or not, he's already been in touch with Honda to make a production-line version. In the meantime, here's a clip of the vehicle in action.
