The marker that was moved eastward a couple of years ago (but then moved back after the most recent dredging) has been move back to the east side of the channel again, and there is a floating green to the east of that. I have been through there in traveling northward last month on a sailboat with a 5' draft staying more or less right down the center and had no problem. I am told that areas to be careful of are on the red side between R2KN and R4, the green side between G3 and G5, and the red side between R6 and R8.
