Stay in the middle.....
Depth is about 20 feet, but sand often gets washed in when the surf's up. Sometimes the waves will break.....but they kind of roll, rather than crash. Like the difference between doheny and the wedge. It can be intimidating when coming back in like the picture. Waves look huge when their coming up behind you. The irony is that the tow boat can't pull the sailboat any faster than it could probably make under its own power (remember the hull speed thing) but the tow probably kept the guy from broaching. I myself would never call the towboat unless something was broken..... Just stay in the middle and go for it. The wave breaks, but quickly but flattens out, because it gets deeper past the entrance and the energy is lost. There's often another sand bar build up about 150 yards further in on the south side. A few weeks ago the lifeguards had a marker bouy there to keep folks in the middle or north side. It was cool. I try to surf those waves in my C 27, it's not that dangerous.
