Don't always believe your chart plotter. Morning after a front came thru i rounded a corner in the ICW to see a sea of red and green bouys. It looked like someone had tossed a box of red and green Christmas ornaments out on the water. All mixed up. I chocked that up to the hairy night before thinking the storm had broke some of the markers loss, so I depended on the chart plotter. Plotter indicated channel was to port, off I went only to run aground on an ebbing tide. The bottom was sand, I could see it clearly as the boat leaned over. No problem, its lunch time anyway and we aren't going anywhere for the next 4 to 5 hours. Beware of Lockwoods Folly Inlet on the ICW.
