I’m not sure I quite follow your narrative that you submitted the recruiting questionnaire and received a confirmation, and then you say it appears like you submitted but no confirmation.
Accustom yourself to not getting instant feedback or response during the USNA application process. It’s not at the Snapchat end of the communications continuum.
There could be any number of reasons for hearing nothing. If you weren’t already on the coaching staff radar, you are probably in a pile with others who submitted their questionnaires. It will get looked at. I don’t know what to tell you about what response you might get. It all depends on what Navy needs and what you have to offer, along with whether you are a viable candidate for an appointment.
You could be proactive and email or call the recruiting coordinator, introduce yourself, mention you have completed the questionnaire, highlight any crew highlights you have, express your sincere interest in Navy, comment on how you are progressing with your application to USNA.
I googled “contact USNA men’s crew coaching staff” for you.
