Where is the Bull Dolphin?

In the last few weeks, I have run across the retirements of some senior sailors that were recognized as the most experienced members of their fields.

The "Bull Frog", the Senior SEAL retired from the Navy last month while the "Ancient Albatross", the Senior Officer Aviator, retired from the Coast Guard.

Both of these items got me to thinking about whether or not the Submarine community recognizes its senior members. The Subvets make a big deal out of the Holland Club for those submariners with more than 50 years of qualification but is there really a recognition for the senior most Submariner on active duty?

The Coasties really get into this kind of thing. In addition to the Albatross, they also have the Ancient Mariner (Gold & Silver) for the longest serving Cuttermen and the Ancient Keeper for the senior most member of the boat service. The even wear the antique style headgear.

So is there a Bull Dolphin?
