Step 5 - Add lights for anchored and aground

Then I added lights for anchored and aground. 

As with masthead lights for power-driven vessels, I could have added a bar above the first W to indicate which one should be higher when there are two, the one in the forward part of the vessel.

For aground, I simply put NUC + W or W+W for anchored. I often think of aground as the consequence of NUC, and once no longer underway NUC must show W or W+W (now fixed to the earth's surface). (Of course, a vessel may have gone aground while under command.... NUC+anchored is just a memory aid for me.)
