Experienced cruisers, Jim and Peg Healy, continue to generously share their observations and advice as they make their way south for the winter. Mt. Pleasant is on the eastern shore of Charleston Harbor. Thank you Jim and Peg!

Today is 10/26/2018. Full moon tides. Sanctuary and Crew Departed Georgetown, SC at 07h30 and traveled to Mount Pleasant, SC.

We transited McClellanville southbound between 10h36 and 19h55. According to Aqua Maps, the tides were +6.08′ falling at 10h36 and 6.0′ falling at 10h55. Virtually high tide; how in the world did I do that?

G35 17.3′
G35A 14.2′ low reading between markers
12.4′
G37 13.1′
11.1′ low reading between markers
R38 11.3′
10.7′ low reading between markers
G39 10.7′
11.3′ low reading between markers
R40 11.9′
11.7′ low reading between markers
R42 14.4′

Subtracting 6.0′ from the least of these depths, MLLW would be (10.7′ – 6.0′) = 4.7′. That DOES NOT account for negative tides during celestial low tide periods. I transited this area in the visual center of the waterway.

We transited the Mount Pleasant range southbound from Isle-Of-Palms to the Ben Sawyer Bridge between 13h49 and 14h05. Aqua Maps put the tide at +1.9′ falling at 13h49.

Mt. Pleasant Bridge 10.6′
10.2′
R118 10.4′
Swinton Creek 8.9′
G117 9.8′
7.3′
Conch Creek 14.7′
7.6′
G119 7.8′
Inlet Creek 12.2′
G121 9.3′

Subtracting 1.9′ from the least of these depths, MLLW would be (7.3 – 1.9) = 5.4′ We found the best water in the visual center of the waterway, which is different from previous years. Again, additional planning is needed for negative tides during celestial low tide periods.
