Frank,
Well, yes in someways.
It was a little confusing when you get into boot camp and start calling things by different names, deck, overhead, bulkhead, hatch, bubbler, etc. I already port and starboard, so those didn't throw me off. All of the other stuff can make your head spin. You pick it all up rather quickly so by the time you hit the fleet you are an old salt and thirsting to use your new vocabulary. Then you find our most of what you were told was so important in boot camp and in A-school was a bunch of Bravo Sierra.
But soon your fit in and after a couple of weeks you are and old salt and you get your sea legs when your out to sea, which is all the time. Then about every 12 weeks or so you loose a portion of the crew and get in a bunch of new guys and it all starts over. But it is all fun. I worked with a couple of ex-Navy at my previous job, we could confuse everyone.
