The fairwater is a structure above the main hull of a
submarine that serves to streamline and protect the
conning tower. If the submarine does not have a conning
tower, the structure is known as the
sail (US) or
fin (UK). On top of the fairwater is the
bridge which is only used when the submarine is surfaced.
The terms
conning tower,
fairwater, and
sail are often (incorrectly) used interchangeably.
