Interesting question all the same, so I looked up other British cargo liners built around the same time from Ben, Glen, and Port Lines. They were all about the same age when they went to the breakers in the mid 80s. I guess containerisation & a recession had a lot to do with this. These vessels were virtually obsolete when built for the work they were designed for. Many of them ended up pottering around the far east and Australasia (Swire, Austasia, etc).
The Taupo, Tekoa and Westmorland all ended up owned by Blue Star's Singapore and Hong Kong companies.
They usually carried meat from Kiwi/Aussie to the Gulf.
The problem was that the ships were not suited for banana trades and were more than 15yrs old and the charterers wanted new ships.
I sailed on Mahsuri and Mandama, which were Tekoa and Taupo, they were indeed lovely ships and very well built.
Yiks, just looked up my discharge book. I was with her on the UK coast August - Sept 1977, left before she went deep sea for the gulf. They were lovely ships, Sulzer RD 90's, English Electric Alternators, no control room but control consoles - happy days!
