At one point, my charts on my plotter had red dotted lines outlining the channel boundries as well as the 25mph zones. They had a solid red line where the no wake zone began on each end. It was VERY helpful to stay in the channels as they turned right and left and certainly knew where the no-wake zones began within the channel. They have suddenly disappeared. Can any direct me to who to set my system so I can get those dotted line channel and speed areas back on my active charts? Thanks
