I'd also hope that you like sailing. One of the prime complaints that I've heard from the Bo's'ns that I knew was that they spent more time at sea, having fewer shore positions than most of the other trades. I, unfortunately don't know if the actual statistics back up those claims, but I frankly wouldn't be surprised if they're right.
That having been said, most of them do seem to enjoy their job. It is demanding, as they are the ones supervising many of the most dangerous evolutions performed in the Navy, such as a replenishment at sea, when a ship is receiving fuel or supplies from a supply ship. To excel in this field requires someone with a good head on thier shoulders, able to focus on many things at once, as well as an ability to react quickly, and correctly, in a crisis. While there are many so-called hard sea trades, this is the hardest (purest?) of them all.
Either way, I'm glad to hear that this setback with the CFAT isn't derailing your plans to serve. Good luck!
