The channel to the north has changed. It is marked, but stay in the middle of the markers. There is a post on the east side as you enter the narrows be sure not to get to close. Then when you get between the fuel docks stay to the east side of the channel, it has shoaled in the middle as you approach the bridge. Be very aware of the current as you near the drawbridge, with the flow has right of way. It can be very fast. On the southside be sure to line up the green posts. the water is very thin on the west side. Have fun, fair winds.
