Queenslander Wayne Jorgensen is busy building his Walkabout as a combined family dayboat and solo expedition craft for use in some of the huge national parks along the coast of north east Australia. Here is a shot of the afterdeck showing the mizzen mast step ( the alloy tube) the tiller mount and the yoke that carries the steering lines back to the rudder stock. You can see the tiller line tunnel down the centerline, the cave lockers each side of that and the boomkin that carries the mizzen sheet out aft of the transom.
