Mark,
I wish I could give you some encouraging information. How low is the low you’re coming off and how high is the high? The San Rafael Channel hasn’t been dredged in years and is both filling in and hard to follow. As I recall, there are (at least) two humps you have to go over coming in and a third when you turn for Loch Lomond. Once you get into San Rafael Creek proper, it deepens considerably all the way to SRYC. To compound the problem, there are only one or two channel marker pilings still in place. For me, it is sweaty palm time all the way in (I draw 6’). Because the channel is no longer uniformly deep, pay close attention to your depth sounder readings and chart plotter position as well as visually sighting the remaining pilings. There are range marker shapes on shore near the creek entrance that you can use to line up on the channel too. I seem to drag in the mud at least once while transiting. You have the right idea going in on a rising tide. Be careful, don’t get distracted, and you will be fine.
