I'm thinking it was based on which shipyard built the boat. I have also read that the USS Shark SS-174 was of all welded construction and i believe the Tarpon was also, which was one of the reasons these two boats were often considered Shark Class instead of Porpoise. I have looked at a couple dive videos of the USS Tarpon and i can't really say for sure one way or the other.

Its actually kind of confusing since some sources claim the USS Shark was the first all welded construction.
