Exactly what Jake said. With competitors on the line, you need to get separation by either capitalizing on their mistakes or slowing down and crossing behind them to run from the waves. I got pinned under someone in this year's Tybee and ended up having to let a wave back me down and run South(the wrong direction) to be able to get clear. In the long run it came out better than getting beat up in the surf and inching through. The surf king himself,Jamie Livingston,clued me in to those tidbits.
Tybee/Worrell Surf rules dictate that the boat going perpendicular to the surf has rights , so keep that in mind when turning down or up.
As far as wave structure if the wind is onshore(on the nose) it will be closed out, offshore will be barreling.

If a man is to be obsessed by something.... I suppose a boat is as good as anything... perhaps a bit better than most.
