Sorry to hear you hit a "Sandbar" in the Dickinson Cr Channel. Strange because Grangers Dredged that entire channel Last Fall, right out into the Bay and the water is at good level. There is a Newly Created berm on the East side of the channel, which is not marked as of yet and is not visible. Most likely that is what you hit. I will advise the Livery and Post`s Marina to get that Berm marked ASAP!
