Anchored off this Cayo for the night in 0.5 Metres of water! It had been a very squally, wet, windy day sailing as a western weather front came through. As we entered the reef system, coming in near a red buoy which marked the entrance, we just missed crashing into a large old buoy mid channel and just under the water popping up every now and again. It could have been disastrous as it was huge.
