I have noticed in the New York environment that in certain locations, such as the container terminal, there are blue, translucent boxes with arrows above them simular to entry and exit points, but they don't show up as such on the charts. I have searched high and low in all the manuals and havn't been able to find an explanation of them. Are they places where you can define unloading waypoints? Also, can anyone offer a suggestion to a beginner on how to define unloading waypoints for the pontoon, and the new barges in the Herc. superpack? Thanx Guys.
