There are 2 dredged channels in G.B.L. The
East is the main channel about 358 meters wide at 19.00 meters depth
and dredged to 19.50 meters for Northbound vessels. The West channel
232 meters wide at 14.00 meters depth dredged to 14.50 meters depth

One to the East for the Northbound convoy.
One to the West for the Southbound convoy.
Each convoy is to keep strictly to its assigned channel.
