This was advertised in our area recently as a class 5. Much larger than that and looks space age so I had no choice but to buy it. At a guess about 3 m wide, square timber stub axles that fit into an aluminium frame fibre glassed into the body. Wheels are 4 ply wide wheelbarrow 16.5 - 8. Front steering casting has broken where it enters the chassis. mast is approx 100mm round section with 3 guys, it has a ball end that sits in a curved hole on the body. A weathered sticker on the front shows Newcastle Boat Mart and a round sticker on the rear seems to show a galleon style of ship. I'm guessing from the East Coast in the 1980's.

That there is a 'SABRE' class yacht....

There was in Adelaide anyway an Orange / Blue one that got HIGHLY modified with a wing mast, wrap around windscreen, Roll cage, Fibreglass rear axles and a suspension front end (from a Vespa scooter)
This yacht was owned by Martin Bell and probably pushed the technology of the Sabre class to the maximum .

There was a RED / White Sabre that was kept in very much 'standard' that was owned by Rodney Dunning that was used on the beaches of Moonta SA (a small seaside town about 2 hrs north of Adelaide).
