Me too, I liked the old names way better, but that's because of the title of this topic. They were born with those names, and I sailed them with those names. I was allways proud to call a port, traffic centre or ship and naming our ships.
The Singapore was indeed nearly ten years younger. She is also a anchor handler (not a very good one), while the rest were plain tugs (exceptionally good ones).
I hate for them to be scrapped, but they are ridiculously expensive to maintain, sail (around 40 tons of fuel per 24 hours when on full power and towing) or insure so it's near i,possible for a non profit bunch of peeps or a museum to keep them. Unless they can berth one and disable the propulsion in order to not need working insurance and just keep her as museum ship. But even then, the scrapvalue is about a million dollars I guess, so try finding someone to sponsor it.....not easy.
