    The Eighteen is a traditional design which has been greatly modernised over the course of its life. Originally a clinker built wooden design, firs built in 1938, it has developed into a much lighter and more standard hull shape with the introduction of GRP hulls from 1969 to an Ian Proctor design, and from 2014 with the adoption of a Phil Morrison design. The latest Eighteen is a performance one design with a three person crew and a single trapeze.

    The Eighteen was adopted by the RYA as a National Class in 1952. The Class embraces all generations of Eighteen, and provides racing for all at the annual National Championships.
