Question 505 Rules of the Road

The correct answer is D) None of the above. A vessel aground would not display the same shape as any of the other options provided. A vessel aground is not towing a submerged object, is not a hydrographic survey vessel at anchor, and is not a dredge underway and dredging. Instead, a vessel aground would display the appropriate day shapes under the International Rules of the Road to indicate her grounded status, which would be different from the shapes required for the other vessels listed.
