The Dart 18 is a one-design 18-foot (5.5 m) long glassfibre sailing catamaran. It is designed to be sailed by two people and can achieve speeds of up to 20 knots.
The Dart 18 was designed in 1975 as a One Design Class by Rodney March, who was also responsible for the design of the Olympic Tornado class catamaran. Up to the present, a number of improvements have been made, but the original concept was preserved though strict class rules. More than 7970 boats have been built up to 2007, which are sailed in more than 16 nations on 4 continents.
The hulls of the Dart 18 are similar to the Tornado catamaran, but without daggerboards. Instead, the lower part of the hulls have skegs typical for a beach catamaran. The hull material is glassfibre. Both hulls are filled with flotation inserts to preserve buoyancy in case of damage. The inside of each hull can be reached through a hatch cover located at the rear of each hull. The boat is assembled by attaching the main and rear beams to the hulls with spring-loaded retaining clips, and lacing the trampoline to the beams. The two rudders are removable without tools, retract on impact with the beach, and can be locked in the up position.
The rigging consists of a rotating mast held by a forestay and two shroud wires. The shrouds can be adjusted by simply moving the bolts in the chainplates. The Dart 18 does not have spreaders. There is a trapeze for the crew.
The mainsail does not have a boom, has 9 full battens, and is controlled by a main sheet with a 7:1 mechanical advantage. The jib sail has 2 short battens, and is controlled by a jib sheet with a 2:1 mechanical advantage. The main sheet block and both jib sheet blocks have a ratchet and a cleat.
A gennaker sail can be added, but is not legal for racing. This is usually combined with a jib furling system.

The UK Dart 18 Catamaran Association:
Bryher Mouldings Ltd. was formed circa 1976 and holds the worldwide copyright and licensing rights to the Dart range of catamarans.
At time of Writing (Aug '09), there is currently no licensee for building new Dart 18's for the UK, although work is in progress to secure the aftermarket and get the supply of new Darts back on track (See this posting (Jan '09) and this statement (Apr '09) in the Dart UK Class Association forum for more information).
Update May 2010: A new Dart 18 was exhibited in March 2010 at the Alexandra Palace Dinghy Show by Windsport International. However, we can't find any information on where/how to buy new boats for the UK. See this posting in the UKIDA forum.
