As I was looking through the list of USCG approved celestial classes, I noticed that some have “Operational Level” or “Management Level” or nothing listed under the class name. Can someone explain to me what the difference is between the op level vs management level class. Is there different material covered? I did notice that the assessments listed under the “Management Level” are from policy letter 04-02. I have a 1600 Master NC and a 3rd Mate NC, wishing to increase the scope to Oceans. Is this relevant to me on which class I take?
