As I was setting a danger buoy over the hump just outside the mouth of the marina I watched two different boats approach the mouth. Both boats continued well west the red buoy just outside the mouth. I was afraid both of them were going to come to an abrupt stop due to the keel hitting a bioherm. This is just to remind everyone one that the lake is still SHALLOW. There is a LOT of SHALLOW reef just to the west of the marina mouth. The Danger buoy and the Green buoy just outside the marina mouth are anchored on or just right near the shallow humps. In order to keep the buoys in place they need a four-to-one scope. This means the buoys will swing on and off the humps. Stay clear of both buoys but favor the green one if you must get close to one or the other. When coming into the marina head for the red buoy and then turn straight for the center of the mouth avoiding both buoys. When leaving the marina, stay dead-center all the way and then head right for the red buoy. The lake is shallow which makes the mouth narrow still. Don't try to get two boats through the mouth at the same time. Nor go out while another boat is trying to get in. And remember the Dinner Boat will take up most of the mouth when exiting and entering. Once he commits to entering or leaving the mouth he is committed and becomes the right-of-way boat because he is now 'limited in his ability to maneuver'. All the reefs are still out there and are still shallow. Remember the Saltair Rule. NEVER sail so you can see the NE side of Saltair. You will be aground on the reef if you do.
