The National 18 is the only three person performance centreboard dinghy with a single trapeze. The Class rules allow for restricted development although the hull and centreboard are now controlled as a one design. The Class is friendly and vibrant with fleets in Ireland, Scotland, England and the Isle of Man racing for a collection of beautiful and historic trophies.

The Design Brief
The brief to Phil Morrison was to design a hull largely consistent with the existing rules, which is not extreme but which is sleeker, lighter, and faster with all-weather performance – and built from modern construction materials and techniques.
The standard specification for a complete “sail away” new National 18 includes the hull fully fitted with Harken and Allen equipment, carbon spars, moulded foils with carbon fibre reinforcing, and racing sails.
Specification and construction
The hull, deck, and cockpit are vacuum moulded, vinyl ester and core cell foam construction with gel coat finish to all external surfaces.
The foils – centreboard and rudder – are also moulded construction with epoxy resin laminated with reinforcing carbon fibre and expanding foam. Foam sandwich is a common construction technique which is strong and robust.
Hull weight 160kg
Sailing weight < 200 kg
Crew weight – No Limit
Main & Jib Sail Area 22.5 m2
Kite Area 21.0 m2
Construction Vinylester Foam Sandwich
The internal layout includes a low full floor with drainage channels leading to a recessed bailer well. The broad central spine supports the centreboard and provides buoyancy. The boat has strong wide decks, a spinnaker chute in front of the forestay, a mainsheet hoop with track, and up to date control systems for trim and adjustment.
The central position of the main buoyancy is to help make righting the boat as easy as possible. The boat lies with the centreboard just above the water allowing easy crew access. The water on board quickly drains through the transom flaps either side of the transom turret buoyancy getting the boat quickly back to racing trim.
The design passed the EU RCD stability tests with flying colours. Each new boat is issued with a sail number by the RYA and White Formula provides a Certificate of Conformity (to the design and approved construction) together with a Hull Identification Number (HIN).
White Formula has over 40 years experience in moulding composite materials. Their mouldings “have reached the depths of the oceans on military submarines to the limits of the skies on British made Helicopters”.
Other classes built by White Formula include the SB20, Whisper, Dart 18, and the ISO / Buzz.
