After what seems like an eternity of not paying much attention to the Zircon, its crew, its history, and therefore this blog, something recently lit a little bit of a fire underneath me to try to find out what happened to the ship after it was sold to John W. Mecom, Sr. in 1973. So, I did a newspaper search hoping that Newspapers.com additions to its collections of newspapers, I’d come across an article about the ship running aground in Corpus Christi in 1988.
I didn’t find anything about that incident, but I discovered an obituary in the 31 August 1986 Galveston Daily News for Bill Curry, whom Mecom had employed as the captain of his yacht.

While Curry died a couple of years before the incident in Corpus Christi, I hope that I might be able to find out from his children (I’ve attempted to contact only one as of yet, with no luck) if they know anything about the ship or have photographs or… something.
I also found this article in the 27 August 1989 Victoria Advocate which, while not about the ship per se, very possibly mentions the name that Mecom gave to to the Nakhoda/Zircon/New York after he purchased it—Grand Mutter.

I haven’t been able to find any other news stories which mention the Grand Mutter, but I’ve sent an email to Mecom’s grandson to see if at least he can confirm that that’s indeed the name that was given to it.
Just as I was about to publish this, I noticed that the latter article above mentions John W. Mecom, Jr. not John W. Mecom, Sr. Possibly it’s a typo or possibly I’m following a dead-end trail.
Edit to add (11 March 2023): After giving this considerable thought, I believe that the Grand Mutter is not the Zircon, but the yacht owned by younger Mecom.
