Shipsterns Bluff is one of the heaviest slabs on the planet—and one of the defining waves of Russell Bierke’s career.

Episode 2 of Watermarks follows Russell and tow partner Zada into a monster session at Shipsterns Bluff, breaking down the wave’s infamous ledge, its warped, stepped bottom, and what it takes to ride it when the swell hits another gear. Along the way, Russell reflects on the wave’s evolution, from the fearless paddle pioneers to the modern tow era he now calls home.

Watermarks is an ongoing series exploring the waves that have shaped Russell Bierke’s career.
