From Kassie James
surfski.info article: “The only way to get outside the reef (aka Out.The. Back.) is through a handful of passes, which (for the non greased toothpick paddlers amongst us) are breaks in the reef. The passes run on the diagonal so are hard to spot. Basically a pass is really-churned-up-water-bookended-by-massive-waves. From Out. The. Back there are Very. Few. Ways. Back… essentially you can go through a pass (voluntary) or over the reef (involuntary). As a tip, one of these routes has a chance of ending better than the other.”
