Marker #32 - Click for Chartview

Captains Chris and Janet are responding to a recent posting relating a very rough passage that adhered strictly to the magenta line through St. Andrew Sound (/?p=130811). Their suggested route below comes complete with a chart. We would like to hear from others who might have made a similar cut close to Horseshoe Shoal to the west of Marker #32. Note Chris and Janet’s very wise tracking of tide during their crossing.

Unless seriously constrained by draft or schedule, a 6 kt boat passing through Jekyll Creek at high tide can cross the outer end of Horseshoe Shoal well to the west of both #31 and #32. We made our first transit of this area 30 minutes after high tide at the Jekyll Marina Station and never saw less than 12 feet on the shoal with wave conditions moderated.
Heading south [from Jekyll Creek], when the magenta line crossed Latitude 31 on the chart, we turned for the old tower on Little Cumberland Island. When the water depth plummeted (west of #32 by 0.6 nm) we turned to intercept the magenta line off #33. This became our standard route.
Caveat, we are unhurried cruisers with 5.5 foot draft. We arrange our days to pass Jekyll, Crooked River, Amelia River #1, and Sawmill Creek #49, each, an hour before high tide.

We have taken a similar path six times across Horseshoe Shoals with our 3ft draft Great Harbour trawler. Our route is more north/south right along 081 25.0 W. We’ve always seemed to transit at half tide or better on both ebb and flood tides and are careful to not let the strong current set us east or west. Correcting for the tide we’ve always seen depths that concur with those charted (7 to 8ft mlw). We don’t turn away from our N/S heading until the depths drop off. Have been hesitant to share this as we are each responsible for our on navigation and have different risk tolerance. With a 3ft draft we are probably more tolerant of 7ft charted depths even in area’s where the significant tidal currents can change the bottom quickly.

Hi All,
I think Capt Chris and Janet have my chart plotter 🙂
That is the course I take every crossing of that sound. Good job explaining how to BTW. As always you are welcome to call for local knowledge at Jekyll Harbor Marina or Tow Boat US. We have several Captains that cross the sound each day ferrying clients to Cumberland and can report on conditions. Hope this helps!

We can confirm the above comments on this route.
Came thru 1 hour before high tide with 5.5 ft draft and never saw less than 12′ of water.

We have crossed this path many times most recent was Jan 12 going South. Always cutting the corner at the angle shown. As soon as we pass R30 we start turning to the light house. We draw 4 ft and have crossed at low tide.
