The crow's nest is designed to look over the bow of distant ships identifying individuals aboard as friend or foe. The height of the nest improves the ultimate safety of the crew and vessel.
Obviously, people who sail the sea are aware the Earth is flat. They observe and commit to the fact of a flat horizon recognizing variance in the atmoplane causing inconsistency when attempting mathematical application to stated observations.
Round Earth believers are sadly mistaken in their claims relative to the horizon and have plenty of opportunities to inquire with the sea faring community to confirm FE claims.
Wow ! And a great big LOL !
I am no expert and I completed my enlistment in the United States Navy many years ago.
But........I would highly recommend that you not tell your story to anyone in the USN.
Just don't talk to any QMC or BMC if you value your life !
Oooooh !......I would hate to hear what their response would be.......LOL
If you are just trolling and trying to post the most nonsensical thing of which you can think or make up....
Congratulations ! You have done very well !
P.S. As I recall, I thnk I read something somewhere some time ago that you wouldn't even be able to see a horizon on a flat earth.
All you would see would be "an indistinct blur which fades away at an indefinite distance in all directions."
Some FE correct me if I got that wrong.
Go down to the shore on a clear day and tell me what you see. Then go to the top story of a hotel near the shore and tell me what you see.
