Five of us had a crack at sailing one landyacht up the Tanami Track a couple of weeks ago. We made 369 klms after six days with occasional moderate but mainly light winds. The hammering from road corrugations, due to the fuel road trains, created metal fatigue in the central 60 ml light wall gal pipe, resulting in the pipe tearing and sagging. Repairs with welded metal sleeves and a star picket only delayed the inevitable. The end came when we sheared our 5/8" high tensile steering bolt for the second time. With the frame twisted 15 degrees, we called it quits.
