CODA : Traveling in the South Carolina ICW
Awendaw anchorage (25 miles east of Charleston), South Carolina
Marc- Travel day of 56 nautical miles from Wacca Wache to the Awendaw anchorage on the ICW. We had an excellent start out on the Waccamaw River with a following 10 knot breeze. We also had to use the tides to our advantage today since several passages on the ICW are very shallow (4 feet or less) at low tide. The timing worked well getting us to the end of the Waccamaw River and into Minim Creek at the hide tide mark. There is a four foot tide here and we used it all.
The Waccamaw River flows southeast to the Atlantic Ocean but about one mile before its mouth is Minim Creek that the Army Corps of Engineers has reconfigured to be part of a series of tidal creeks connected by manmade ditches to make a navigable waterway inside of the barrier beaches and islands. Great engineering that works well but needs constant maintenance (otherwise known as dredging in certain locations).
The water source is both through Inlets from the Atlantic Ocean and fresh water creeks. Because the waterway is open to the ocean it is subject to tides. In this part of the coast you have tidal changes every six hours giving you two high tides and two low tides daily. When we came down the Waccamaw River we were traveling at 6 knots fighting a 1.5 knot current (the tide was coming in or rising). As we turned the corner into Minim Creek that current turned in our favor bringing up our boat speed to 8 plus knots. CODA's actual boat speed through the water was 7.5 knots all day (except when we plowed through some very soft mud).
Speaking of mud as we drew closer to our destination the tide had gone out bringing us closer to the red zone of the Army Corps of Engineer surveys found on one of our i-pads. The red zone indicates depths of 4 feet or less (we need 5.3 feet to float CODA). There are blue zones and green and yellow which are all fine for us. CODA has a powerful diesel engine and a rather large three bladed propeller that allows us to plow, or push, through soft mud as we did today for the last mile or so of the trip with a reduction of speed to about 6 knots.
The Awendaw anchorage is really an enlarged section of a creek that leads to an ocean inlet. In fact some of the boats anchored here appear to be facing the open ocean. If we look past the six sailboats anchored to our east we can see the Atlantic Ocean. It is very calm in here for whatever reason.

I too love seeing anchor lights, just not too many! Sounds like a lovely day.
