Shipstern Bluff.

Shipstern Bluff is a single right-hand slab on the Tasman Peninsula in southeast Tasmania, ~90 minutes south of Hobart, breaking under the 300 m dolerite cliffs at Cape Raoul. The wave is famous for its second ledge, “the step”, a backwash double-up that throws the lip clear of the takeoff and turns most rides into something between a ramp and a free-fall. There’s no road in. Get there by boat from Pirates Bay (a 30 km, ~40-minute trip) or hike an hour through Tasman National Park from the Cape Raoul carpark. Andy Campbell put it on film in 2000, and Red Bull Cape Fear ran here in 2019 and 2021.

The lineup needs Southern Ocean energy. Best season is June through August, when Roaring 40s lows track east under Tasmania and pump west to south-west swell. The window is narrow. Period under 12 s won’t stand the slab up; over 16 s the step gets unmanageable. Working size is 2.5 m and bigger, with the heaviest paddled sessions sitting at 4 to 5 m. Offshore is north-west to west. Tasmanian weather flips inside an hour, so the call to launch the boat is usually made at dawn off the swell model and the synoptic chart, not the day before.

The wave is what’s dangerous. The water is dangerous too. Winter sits at 10 to 12 °C, summer caps at 21 °C. A 5/4 with hood, boots, and gloves covers winter, a 4/3 is the summer minimum. The slab runs over shallow dolerite with a dry-rock section that exposes between sets. Wash through to the headland and you’re in cold water on shallow reef, 30 km from a road. White sharks live in Tasmanian water. So do aggressive sea lions. The paddle audience is a handful of local specialists, Tyler Hollmer-Cross and Marti Paradisis chief among them, plus visiting pros on tow assist when it’s truly heavy. If you came to watch, stay back from the headland. The washes do not negotiate.
