I thought some of you BI guys would like to see a couple of pictures from early 1964 - Built by Barclay Curle, Glasgow in 1926, RAJULA is shown leaving Madras and the 1960 Harland & Wolff, Glasgow, BARBETA is in the River Hooghly. This class of 5 ships by same builder were the first British merchant ships to have all a.c deck machinery - a combination of the conventional winch/derrick arrangement and cranes. A 6 cylinder Harland -B&W engine of 6700 bhp drivibg a single screw gave a speed of 16 knots.
Very modern in appearance but in my opinion lacking the classic look of the larger turbine ships WOODARA and WAROONGA of the same period.
I was with Brocklebank at the time so I guess it could be argued I am not one to judge elegant ship designs.

Barbeta

There has been a long and protracted correspondence in various marine journals re the first with all AC. Some quote the Hunstland, others the Mangla, certainly the Maskeliya and Maturata had first two AC winches as a trial
I guess the arguements as to which British ships were first to have a.c electrics is on a par who reached the summit of Everest first - was it Hillary or Tensing.
I cannot comment on Hunstland but the Brocklebank ships are not in the contest. Maskeliya had a couple of ac winches that could not have been successful as they were replaced by steam winches. Her a.c power generation was primitive - a.c alternators driven by steam recip engines - carbon pile voltage regulators. Mangla and Mathura of 1959 and 1960 had 440 v a.c. power. However deck machinery was d.c conversion from a.c either by transformer or motor generator set. - a.c variable speed drives being in their infancy in those days.

Barbeta

I wonder which 'Strath' She became? (Thumb)
As far as I know Barbeta never became a "Strath---".
She was sold in 1971 to Sudan Shipping Co. and renamed MARIDI.
A further sale in 1980 to Sea Faith Nav. Panama saw her renamed SPIJKENISSE. She was broken up at Gadani Beach, Pakistan in 1980.

Tom,
Glad you liked the photos of Rajula and Barbeta. - I remember reading about the "B-Class" ships when Bulimba was featured in the "Motor Ship" magazine, the settee to bed conversion being a feature. - How successful this worked in practice would be interesting to know.
