Kraken 18 was a day racing trimaran sailboat designed by Lock Crowther in the wake of his successful Bunyip 20 design,^[1][2] as a scaled-down version of the earlier Kraken 25 with similar performance.^[3] Its smaller size and folding beams made it more practical and led to its greater success.^[3]

Advertised as "a slightly faster, more attractive version of the Bunyip 20 with round bilge hulls",^[1] it shared an identical rig with the Bunyip 20^[1] but was 2 ft (0.61 m) shorter.^[1]

It was accepted as a class by the Victoria branch of Trimaran Association of Australia, making it the first one design trimaran class in Australian history.^[3]
