Waitara

It's one of four sisters from the fleet of Rederi AB Transatlantic, Gothenburg. They were KILLARA, WAITARA, TALARAH and WOOLLARAH. They were engaged on the Europe-Australia trade.The only one i saw in the London river around the time of this photo was TALARAH.

Nice looking vessel, twin funnel, too

Thanks Bobs for your help on this and the others, with your suggestions I have found her I.D.

bowatersteamships ; I wonder what load those derricks could handle? They don't look too substantial.
I remember Lloyd Brasileiro had some twin funnellers (amidships) in 1947.

Good shot of her here;

Thin derricks were common on refrigerated ships as the load was not great, speed being the main requirement. These are cranes and the jibs look long compared to most so the intended cargo may have been light in weight. Package lumber may have been the prefered cargo outbound from Scandinavia but what of a home bound cargo? There are eight cranes so they could have used two to lift heavier cargo loads, a delicate control needed by the crane ops when lifting and slewing.
The ships were 512 feet long and 70 feet wide so they were large ships for their day.
