I love the magenta line!

When traveling the ICW in Florida, our chart plotter usually has a magenta line that clearly marks the deepest parts of the channel.  There are times it disappears!  According to the instructions, it disappears when the frequent shoaling makes it impossible to have a consistent channel.  At those times, we must use our depth finder to poke along and find our way through ICW.  Those are the times Gay makes sure Ken is at the helm--because remember, if you are not touching the wheel when the boat runs aground, it cannot be your fault (since we have not run aground, it appears that Ken does just fine without the magenta line).
