Kraken 18

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]

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]

The Kraken 18 was perhaps the most successful of the three designs, performance was said to be almost as good as the larger boat and its smaller size combined with folding cross beams made it more practical for the average owner.
