Here is about how it was when I went across the equator in the 1980's now it's watered down today from what I hear plus on ship it's not all male any more. You tube video of a carrier in the 1980's about the same as when I went across the equator, Wog Day Afternoon - YouTube
And another youtube video from the 1930's Neptune's Realm - The Bizarre US Navy Equator Initiation Ritual - YouTube
And when they say bizarre they are not kidding
I heard some college initiations can be rough does our US Navy college of hard knocks beat it going over the line from that video above ? The navy use to do it in large scale my ship had a crew of 1200 so about 600-700 went through it. That carrier had about 5000 crew so over a 1000 or more initiated at one time. When you became Chief petty officer they use to have a real bad initiations none of those chiefs had the guts to tell us lower enlisted how bad it was. That mite be gone now to.
