The Phoenix 18 is an American catamaran sailing dinghy that was designed by Dick Gibbs and Rod Macalpine-Downie and first built in 1964.
The boat is a smaller variant of the Shark 20 and a development of the Thai Mark IV.
The boat was named after the mythical bird as it was the first design built by the Gibbs Boat Company after its factory burned down.
