The S.S. Mongolia (3) was a well built steam turbine-driven twin-screw Passenger Liner, built for the “Peninsular and Oriental Steam Navigation Company” (P&O) and she was launched in 1922. However, she was the last of the three P&O liners built with the name of “Mongolia”. Amazingly, although the last with the name, she is the only P&O ship to have been either chartered out or sold on number of times and she had four new names as can be seen on the logo of the R.M.S. Mongolia above.

It is for this reason that this feature has three pages, although under different names, but listed as Page One, Two & Three in the Index at the bottom of the page.

However, let us first look at the two S,S, Mongolia’s before the one in question, and below are their details, which I will keep as brief as possible.


S.S. Mongolia (1):

This fine triple masts steam-sailing ship was built by Scott & Co., Greenock, in their Cartsdyke East Yards & Yard No. 106. She was launched March 1, 1865, and delivered to P&O in August 1865. Her dimensions were as follows; 2,999 GRT - L 319.4 ft: W: 40.2 ft: Depth 32.7 ft. She was scrapped in Bombay in November 1888.

S.S. Mongolia (2):

This time P&O decided to construct a two funnelled liner and she was built by “J  Caird & Co.,” in Greenock, Yard 302. She was 12,358 GRT, and her dimensions were Length: 168, Breadth: 19 m & Draught: 10.7 m, she has twin screws and an excellent speed of 19 knots.

During a voyage in June 1917 filled with passengers, and mail bound for India, China, as well as her holds filled with general cargo bound for Australia, she suddenly struck a mine on June 23, 1917 some 50 miles S/W of Bombay. Apparently, this mine had been laid by the German raider the SMS Wolf.

The mine caused an explosion, which saw 3 passengers as well as 3 officers in the engine room and 14 native and 3 European crewmembers were killed by the fiery and wild explosion. All the ships survivors from the Mongolia were rescued without any further loss by nearby vessels, but obviously it was not possible to save the Royal Mails that sadly went down with the ship.

She was a fine and a reliable ship, but had a tragic ending in Indian waters



Mongolia (3):

P&O ordered the third ship that would be named “Mongolia” from the Sir W G Armstrong, Whitworth & Co. Ltd. of Newcastle upon Tyne on 22 November 1918, at an agreed cost of £1 million (English Pounds).

However, due to post war refits of existing ships her construction was delayed and her first steel plate was laid down in due course in yard No. 964. When ready, she was finally launched on August 24, 1922 and once in the water she was towed to her fit-out berth where she was completed. When this fine new ship was completed she undertook her deep sea trials on April 25, 1923 with great success as she managed a remarkable top speed of 17.6 knots, although she would usually sail at a service speed of 16.5 knots. She was delivered the next day.

Here we see a starboard side-view of the Mongolia’s deck layout

The R.M.S. Mongolia was completed and delivered to P&O in London on April 26, 1923 and P&O made the ship ready for her maiden voyage.

R.M.S. Mongolia Maiden Voyage:

On May 11, 1923 there were great crowds of people, let alone passengers travelling to various destinations, as well as migrants who were heading off for a new life in Australia. As the time for departure arrived, her decks were packed with her passengers whilst family and friends filled the dockside and streamers were flying with everyone holding on, and the band played, thus as she blasted her horn as she pulled away three times it was an emotional time for all, especially as the streamers finally broke the bond of those on board and the loved ones ashore. As she headed out to sea it became an exciting new adventure, but as this was also was a brand new ship made it even more exciting for all the passengers, and the same applied for the crew and a proud master on her Bridge taking her out on her maiden voyage!

The R.M.S. Mongolia having departed London on her maiden voyage bound for Sydney, and this would became a four-weekly mail service for several years. Her ports of call were as follows; London, Gibraltar, Marseilles, Port Said, Aden, Bombay, Colombo, Fremantle, Adelaide, Melbourne, Sydney and return.

Ship details and photographs of decks and interiors:

The 16,385 GRT R.M.S. Mongolia accommodated 230 First Class and 180 Second Class passengers, and she had and able officers and crew of 353 persons.

However, it should be noted, that the R.M.S. Mongolia was actually considered as being a “passenger-cargo ship”, as she had six holds, three forward and three aft, with space for 669,000 cu ft (18,900 m3) of cargo, including 136,000 cu ft (3,900 m3) of refrigerated space, as she would bring back meat and other foods, etc from Australia and spices from India, etc. And not to forget her being a Royal Mail Ship, this she carried mail to various countries, especially Australia.

The Mongolia had a length of 573 ft - 175 m and she was powered by six double-reduction-geared steam turbines, having two screws 13,000 SHP, and had a service speed of 16.5 knots. Her engines were built by the ships builders, “Armstrong Whitworth.” For complete details see her specifications below.

on this postcard they designated her as just being a  … S.S. (Steam Ship)

In 1925 another ship was added, thus the Royal Mail service now became a fortnightly service. The Mongolia proved to be a successful ship and Passengers, in both classes were very happy with their voyage and their overall experience with the food, service and activities, etc.

In 1928 it was decided to convert her to operate her on oil-burning fuel, which was a great improvement, and she continued on her successful career. Operating as follows; London, Plymouth, Tangier, Gibraltar, Marseilles, Port Said, Aden, Bombay, Colombo, Fremantle, Adelaide, Melbourne, Sydney, Brisbane, and return.

As the Mongolia continued her excellent career sailing to and from Australia, via what was called the spice route, there were a number of events this fine ship could have done without. One of these was a collision on July 16, 1933 with a tanker by the name of “British Venture” and a breakwater in Copenhagen. She even ran aground at little later but she did manage to get loose and continue her voyage without any real damage.

The M/S Villa de Madrid Incident:

But on December 3, 1936 whilst close to Marseille the R.M.S. Mongolia collided with the Spanish “Compañía Trasmediterránea Line” passenger liner, the M/S Villa de Madrid, and here are some details regarding this fine 6,942 GRT ship that sailed for an amazing 47 years.

M/S Villa de Madrid

This beautifully balanced looking ship was built by the German shipyards “Krupp Germania Werft AG”, Kiel and her first keel plate was laid down in Yard 515 in 1930. She was launched and named on June 6, 1931. The ship was finished and was almost ready to be delivered to her owners the “Trasmediterránea CompañíaPlease Note: This is not the company that ended up owning the ship after she was completed.

The reason for the afore-mentioned notice is that when the final trials and tests were carried out, she did not reach her contracted speeds, and the ship was rejected by the intended owner. Instead of fixing the problem, “Krupp Germania” announced the she would be sold at a public auction. However as there was 0nly a single buyer present who were willing to pay the amount asked for her, which was lower than the one originally agreed with the original owner, but the offer was declared void due to there not being any other bidders. Therefore “Krupp” announced another auction, and this time they received an even lower price then which was agreed to at the earlier auction, and this time she was sold to “Compañía Trasmediterránea” (yes a similar name but “Compañía” for this company is before “Trasmediterránea”, whilst with the original owner it came after), once again they being the only company that actually submitted a proposal, and thankfully the ship having been reregistered she retained her original name; “Villa de Madrid”.

Having received her new livery she was placed on what was known as; “Linea Gran Express de Lujo, or the “Luxury Grand Express Line” from Barcelona, Cadiz to the Canary Islands with intermediate ports of call.

In July 1936 the M/S Villa de Madrid was ordered home to Barcelona, due to the commencement of the Spanish Civil War and she was confiscated by the authorities and was used temporarily as a prison ship, but then later in that year she was operated as a liaison ship between Barcelona and Marseille. It was during one of these voyages to Marseille that the R.M.S. Mongolia and the M/S Villa de Madrid collided, however, both ships seem to survive without too much damage and were able to continue, The Spanish ship sailed on and from mid 1959 to July 1962 she received an extensive rebuilding program, which gave her a new longer streamline profile, with a more luxurious interior than she already had. She continued sailing and was only broken up in 1979. There is more information of her, as well as exterior and interior photographs online.

The final days for P&O’s R.M.S. Mongolia: 

After the incident with the M/S Villa de Madrid on December 3, 1936, the R.M.S. Mongolia made several more voyages to Australia, but these would be her final return sailings to Australia.

When R.M.S. Mongolia arrived home to London in July 1937, P&O laid her up and placed her on the market hoping to find a buyer for her as she was still in an excellent condition. But at the time there were no buyers to be found for her, yet amazingly she would have four new and very successful lives in the future and her next stage will be revealed in detail below the Mongolia’s Specifications, etc.

S.S. Rimutaka (3):

New Zealand Shipping Company House Flags

It would be on May 7, 1938, that P&O transferred the now prefixed S.S. Mongolia under a long-term charter agreement to the “New Zealand Shipping Company” (NZSCo) being a P&O subsidiary, who renamed her “Rimutaka”, but she remained registered in the UK.

Here we see the S.S. Rimutaka in Wellington, the Capital of New Zealand early during her new career

She was in fact the third ship to carry this proud Maori name for the company, thus she was S.S. Rimutaka number 3, and the name originated from the beautiful mountain ranges in New Zealand, and all ships operated on the traditional NZSCo’s voyages between the UK and New Zealand, sailing via the Panama Canal.

S.S. Rimutaka 1 & 2:

The first ship to proudly carry this name was the beautiful S.S. Rimutaka (1) of 1884, was built by “John Elder & Co”, Glasgow and launched in October 1884. She had a steel hull and had a magnificent clipper bow and was 4,473-ton liner and featured three-masts, thus she could sail under both sail and steam. The New Zealand Shipping Company operated this fine ship until 1899; the reason for her demise was that a new and larger ship had already been ordered. A photographic postcard of her can be seen below.

Look at her, for this is sheer maritime beauty!

The second was the S.S. Rimutaka (2) which arrived on the scene in 1900. She was built by “Wm Deny & Bros”, Dumbarton, Scotland. The 7,765-ton liner and operated until 1929, a good nine years before the before the arrival of the new ship to arrive and carry this proud name in the company history.

A painting of the S.S. Rimutaka (2) is seen on the NZSCo postcard



Back to the S.S. Rimutaka (3):

The NZSCo reconfigured the S.S. Rimutaka to carry 840 Tourist Class passengers and her Public Venues were all upgraded somewhat, upon completion of her refit she was registered at Plymouth in the UK.

However before entering service, she somehow collided with Corfleet off the Nore causing some damage, thus after repairs were completed, and the S.S. Rimutaka finally departed on her maiden voyage on December 12, 1938.

Thus she commenced her regular service from London, through the Panama Canal, to Auckland, but she would then head south as she would terminate her voyage in New Zealand’s Capital, Wellington.

She suffered a fire in hold No. 3 on March 9, 1939, which was rapidly extinguished and no great damage was done to the ship. Sadly her role as a passenger liner was very short, for in September of 1939, she was requisitioned by the British Government to be converted into an armed merchant cruiser due to the commencement of World War II on September 1.

However, she was released before any actual conversion took place, and there are doubts what actually happened to her during this time and her next call as follows. The Brit’s once again requisitioned the Rimutaka, but this time for their “Liner Division” to operate from May 15, 1940 to June 14, 1946, thus she remained on UK to New Zealand service for most of the war under British command, but the ship was managed and operated by NZSCo!  After hostilities ceased, she was officially returned to the NZSCo and she continued on her original civil duties.

A post war postcard of the S.S. Rimutaka

The S.S. Rimutaka continued her regular duties and she would make occasional visits to other ports in New Zealand, such as Lyttelton (Christchurch) and Port Chalmers (Dunedin) in the South Island of New Zealand.

She continued as a very busy ship for a full years, however considering as less inexpensive new and larger motor ships were coming on the scene, the Rimutaka was becoming redundant having been a much loved KIWI ship for 11 years, and thus she was about to be returned to her owners P&O London.

S.S. Rimutaka’s final voyage for the “New Zealand Shipping Company” departed Wellington for London very early in January, 1950, and upon arrival in London the ship was returned to P&O, who already had a buyer, as she was sold on January 10, 1950 whist the ship was on her voyage home.
