Abigal Taylor 7053583398 - Wave Slab Fury from Oz br Traditional surfing waves roll toward shore, slow down as they rise up, and break cleanly to one or both sides. A slab wave moves fast, through deep water, and hits a shallow reef at full speed. It lifts out of nowhere within seconds, sucks the water out of the shallows in front of it, and then slams shut in a violent thump. The power and danger of a slab come as much from the thickness as the height. For a surfer, riding one of these beasts is like escaping from a collapsing parking garage.
