Welcome to the National 18 class website.

The National 18’ began in 1938 following a design competition organised by the then YRA (now RYA) and Yachting World magazine.

The original idea was that of Frank Knowling of Whitstable YC (later to be known as the father of the class) for an 18-foot sailing dinghy, suitable for day sailing, yet fast enough to be of interest to racing sailors and at a reasonable cost. (The first rather hopeful restriction of the original class rules was “Price not to exceed £125 complete with spars, all equipment and designer’s fee but not including sails”). The plan was to produce an affordable national alternative to the many local one-designs of about this size to be found right round the coast of the British Isles.  Many of these local estuary classes survive today, for example the Mermaid in Dublin, Thames Estuary OD, Chichester Harbour 18 etc.

The well-known designer Uffa Fox won the competition (over the Laurent Giles submitted version) with his ‘Ace’ design for a clinker-built wooden boat. National 18’ number 1, ‘Hurricane’, was owned by Stanley Beale and sailed at Whitstable, with No.2 ’Gust’ and No.3 Foam’’. 

Initial enthusiasm was held back by the effects of World War II but a good deal of 18’ building got underway soon afterwards, when mahogany was again available for boat-building and the class became active especially in the Thames Estuary area.  By 1950, fleets had appeared at clubs dotted all around the British Isles and Ireland, the Class Association having been formed in 1947.

Although most boats were built to the ‘Ace’ design, the class had always been ‘restricted’ rather than ‘one-design’ and boats with a reduced number of wider planks were built when glued plywood construction was adopted and even one moulded carvel boat was built (252 ’Sabon’)
