Pictured here is Railay Beach, Thailand. It is considered to be the 9th most beautiful beach in the world. Drawn up on its white sands are several traditional Thai long-tailed boats. These feature repurposed automotive engines mounted on a swivel pivot at the stern. A long propeller shaft extends 2 to 4 meters (3ft. to 12ft) directly into the water, allowing the driver to steer and tilt the propeller without needing a rudder. The long-tail design lets boatmen lift the propeller completely clear of the water, making it easy to glide over shallow coral reefs, sandbars, and tide flats without damaging the propulsion system.
