Surf: The perfect name for the most difficult and technically demanding left in the Mentawai. A seemingly endless fringing reef stretches down the west coast of Karangmajat Island causing cylindrical, lefthand barrels to wink at viewers anchored on the NW corner. The featureless line-up makes it hard to know if you are in position and only an air-drop to full tilt, in the barrel, speed pump will be good enough to get into the wave and have a chance of weaving through some of the cavernous sections that spin off down the 500m straight reef. Rarely backs off enough to allow turns, this is a tube-fest of the highest order. Perfect conditions are SW swell, light E wind, mid to high tide and at least 8ft faces as the reef is bloodthirsty when small. Not too consistent, not too crowded and not for everyone!
