I really like your anchoring guides. However, I think you have some flaws in the entry you have for Cowen Creek. (Mile 544.5 on the Beaufort River, between Beaufort SC and Hilton Head). I’d like to suggest some corrections on this one.
1). I think it’s misleading to talk about “negotiating several unmarked shoals”. Yes, if you’re coming from the north, you must go far enough south to clear Cowen spit. If you watch your chartplotter, the entrance to Cowen Creek is wide and deep with NO UNMARKED SHOALS. Take a look at the wider area chart, and this should be self-evident. From the south, it’s a no-brainer. Coming from the north, you’re in good shape if you go far enough south to go around the south side of the old range light charted at 32 degrees 20.12N, 80 degrees 39.34W. Do that, and it’s a wide and deep water entrance with no issues.
2). Your little anchor symbol on the chart photo is way upstream in the creek. Yes, it gets narrower up there, but it’s all protected and nearly always flat water once you’re in the creek. Most cruising boats don’t go that far up to anchor. I’ve seen 3 or 4 cruising boats anchored in the area 32 degrees 21.64N, 80 degrees 38.89W. ( Middle of the creek, abeam of the “o” in “Cowen Cr” label on the chart.)
3). Optionally… there’s another anchorage area for someone who really wants a “Hurricane Hole”. It’s the straight stretch of the creek, t32 degrees 22.99N, 80degrees 38.54W. There is deep water all the way there so it allows even a sailboat to reach these areas, going past private docks on Distant Island and around a double set of bends. It is really protected. .
FYI… ( my credentials for sharing this…) I’m a full time live-aboard cruiser, and spend half of my time living in the Beaufort area and half time cruising on a 38′ sailboat. Cowen Creek is a nice, nearby wilderness anchorage, a few minutes away from the marina. It’s where I take “visitors” when they come to visit my wife and I, and they want to spend a night on the sailboat anchored out. (Smile!).
