I realize this is an old post but I was looking up online "What is Captain's Mast" after something my sailor had shared with me and this was the second listing, after Wikipedia, that came up in my Google search. Thank you very much for this information, I am glad you posted it.
This was great information. I hope I never need it. Adult or not, should my sailor be reviewed as such he has more to fear from me than the captain! ... granted that may be more easily said than done, but I'm allowed to live in my own world! :)
What are some violations that would merit a Captain's Mast besides those already mentioned?
Jwn's Mom - is there something specific you are wondering about? I don't know "other" violations but I believe the severity of what is punished may depend also on the "site" or base and how the incident affects others civilian or military. For example, at NNPTC the Nuclear Training program, they are very strict on owning up to your mistakes. So, if an incident occurs and they think a sailor is lying about their involvement, they may bring them up for Captain's Mast, mostly to evaluate their character. That is only my secondhand understanding but just an example.
Certain bases and training areas around the world may have a lot stricter rules on drinking, even over age drinking, depending on how the sailors have interacted with civilians and military in the past. So, if the captain believes a strict precedence needs to be set, there may be more masts for those violations at one base or location than at others.
The link below is to the UCMJ (Uniform Code of Military Justice). Any that would be considered non-judicial could/would be something to warrant Captain's Mast. There is also a "General Article" (134) that might/may encompass something that is not specified within other articles.
I have had Non-Judicial Punishment. In the Marine Corps we call it Office Hours. In my case there was no errors to be corrected leading up to my NJP. It just happened from one incident. Why? Because the person who initiated it, was a outranking E-6, I was an E-3, who didn't like being rebuffed of his advances toward me. He was successful in setting me up and seeing me punished. Mind you this was 30 years ago and reporting avenues for such treatment are vastly better. In my case he even reported me to NCIS (NIS back then) for having an affair with an E-7. I had duty logs to account for my whereabouts in that circumstance and was newly happily married. These Jack-wagons are few and far between these days and like I said, reporting of harassment is much more supported.
I ended up receiving a weeks forfeiture of pay, 2 weeks restriction to barracks (I lived off base with my husband) and 90 day delay of contracted promotion. Funny that when I was moved away from his office and direct supervision, I never had another disciplinary accusation brought against me again, until that NIS report which was totally false.
Like has been said, it is Non-judicial and as long as you learn from it and move onward and upward in your Navy career, it is but a blip on your rear horizon. If you have any questions, message me and I'll help if I can.
