Ian Aitken’s JACKNIFE is “the world’s first 11m, folding, trailerable proa with freestanding wing mast”.
Although inspired by Rob Denney’s Harryproas, the craft was designed and built by Ian and ‘Barn Job Innovations’ of Taranaki, New Zealand. Well named, the craft unfolds like a Swiss Army Knife, only with more moving parts. Read more at Harryproa
