Austral was a custom design for Chris and Penny Morton, who built their boat An Old Captivity in Australia. She fell into disrepair after they sold her, and is now being rebuilt (photos below).
Austral is a moderately heavy boat (11,000 lbs), with a displacement/length ration of 307. Just over a third of her weight (3,850 lbs) is in ballast. Her displacement is calculated with a full complement of cruising gear. She is easily driven by the either gaff or Bermudan rig, both of which spread about 500 of working sail.
Austral is designed to be strip planked, with fiberglass sheathing or veneer overlay.
