Holy moley today was peak ICW. I think we will go outside tomorrow. We started the day with a swing bridge and 3 MILES of something called "The Rock Pile". The name says it all. Thankfully a nice Endeavor 42 came out right before us (another Aquamap user!) so we followed him most of the way to Georgetown. (I know it was an Endeavor 42 because some guy sitting on his deck in Myrtle Beach radioed him to compliment the boat and get the make and year. It was awesome.) We went through another dozen or so bridges (at least 3 swing bridges) and the last one (Ocean Highway Bridge just outside Georgetown) pinged the antenna! This one wasn't even supposed to be iffy but it was for sure not higher than 63ft. However, we did come in at high tide so that certainly contributed. Of course there wasn't a measurment board to check on this one before we went under. The good part about coming in at high tide is that the very very worrying deep red "channel" into Georgetown harbor was closer to 9-10 ft than 6, so hurrah. Next high tide is 4:30 am so we plan to leave early. There was a very scenic bit of winding river through a forest with actually reasonably deep water for a while this afternoon so that was really lovely. We also saw a sun dog, and a pack of sea gulls who were following us like dogs begging for scraps. They kept swooping and hovering beind us and cawing.
