The Naiad 18 is a Canadian trailerable sailboat, that was designed by Mark Ellis, first built from 1984 to 1986, and named for the mythological water sprites.[2][3][4]
Production
The boat was built by Luna Yachts in Oakville, Ontario, Canada, between 1984 and 1986, but it is now out of production.[2][4] It is believed that 20 were completed. Although one was destroyed, by 2013, 19 remained in service.[1]
Design

The Naiad 18 is a small, open, recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cat rig, a plumb stem, a vertical transom, a transom-hung rudder, a wishbone boom and a centerboard that folds up into a trunk. It displaces 1,100 lb (499 kg) and carries 550 lb (249 kg) of ballast.[2][4]
The boat has a draft of 3.67 ft (1.12 m) with the centreboard extended and 0.67 ft (0.20 m) with it retracted, allowing beaching or ground transportation on a trailer.[2][4]
The boat can be optionally fitted with a small outboard motor for docking and maneuvering.[2][4]
The design has a hull speed of 5.61 kn (10.39 km/h).[4][5]
