Delta Line – The last truly American flag passenger steamship company.

Delta Line (Mississippi Shipping Co.), New Orleans (1919-85)

Cruising The Past looks at the Delta Line.  They provided service from Gulf of Mexico and east coast of South America; originally established by coffee merchants to ship Brazilian produce directly to the Mississippi Valley through New Orleans, bypassing New York. Officially the Mississippi Shipping Company until 1962, but was already known unofficially as the Delta Line long before that.

The line’s management failed to buy container vessels in the 1970s, lost so much money that its owners (by then the Holiday Inn Corporation) sold out to Crowley Maritime, the largest US barge and tug operator, in 1982.

The Del Norte and her sister ships – Del Sud and Del Mar were most distinctive and revolutionary ships.

They were the pride of the Southern Hemisphere and soon became synonymous with revival of the Delta Line’s service from the USA to South America after the Second World War. They were “resorts at sea” and fully air conditioned and the last word in ocean comfort.

Design and Construction (1946 – 1947):

The Mississippi Shipping Company of New Orleans introduced three revolutionary passenger-cargo ships to its South American services in the post-war years of the 1940s.  In keeping with the trade name of the company, ”Delta Line”, the three vessels were given  “Del” names Del Norte, Del Sud and Del Mar.  The three “Dels” unusual design,  by the naval architect George G. Sharp of New York,  made them unique along the New Orleans waterfront and the east coast of South America,  an area where they had traded for nearly a quarter of a century.

The liners were originally based on standard C-3 design cargo hulls, all that was available for purchase during the late war years.  With the cooperation of Admiral Vickery, head of the construction division of the American Maritime Commission, Delta Line arranged that three of these hulls be redesigned as passenger/cargo vessels to re-establish the company’s services to South America.  The ships, built at the Ingalls Shipyard, Pascagoula, Mississipi, were fitted with D.R. geared turbines giving a 17 knot service speed.  A new innovation for the time was complete air-conditioning throughout the accommodation areas for passengers, officers and crew.  Being nearly identical, the sister ships were all 10,074 tons, 495 feet in length and 70 feet in breadth.  Their total cost in 1946 was over $7,000,000 each.

The Del Norte was the first ship of the trio to be completed. She sailed on her maiden voyage to Buenos Aires on the 26th November 1946.She was soon followed by her sister ships: Del Sud (28th March 1947) and Del Mar (13th June 1947). Once in service the three passenger/cargo liners maintained a regular schedule of two sailings per month from U.S. Gulf ports to the Caribbean and South America.  The “Del” trio quickly established an enviable record for dependable sailings and were soon offering 44 day round-trip cruises to such ports of call as Rio de Janeiro, Santos, Paranagua and Buenos Aires.

The Delta Line era (1946 – 1967):

Life on board the “Dels” was an leisurely affair. One could start the day with a stroll along the glass enclosed Promenade deck, a visit to the ship’s library – or breakfast in bed.  The latter “institution” was served with a full view of the sea sliding by outside through sem-square “windows” which had replaced the traditional round port hole in many cabins.  Mid-morning coffee was served in the main lounge, a room decorated by murals of “old” New Orleans.  Glass partitions separated the various public rooms, yet, at the same time, created an open spaciousness associated with much larger ships.  Days were lazy and relaxed with games available on the sports deck or a long siesta in one of the comfortable lounge chairs awaiting passengers out of the wind’s way on the aft deck.  Evenings had their beginnings in the ship’s dining room, then were continued in the Grand Lounge while the band played – or on warm, tropical evenings at poolside.

On deck a dominant feature of the new ships was the huge funnel – actually a dummy built of aluminium.  Inside this structure were two decks of officer’s quarters, the main radio room and an emergency generator.  The actual exhaust gases were discharged through two thin stacks just aft of the dummy funnel, somewhat disguised as kingposts.

<>The vessels were among the first commercial ships of the world to be equipped with post-war radar, highly refined after stringent wartime use. A scanning screen with three ranges of visual presentation gave the navigating officers views at 2, 6 and 30 nautical miles, a comforting factor in the highly congested waterways of the Mississipi Delta and River Plate.
On departure from New Orleans, the ships sailed southwards through the Caribbean to San Juan (Puerto Rico), then to Bridgetown, Curacao and La Guaira. After this the ship headed out into the South Atlantic round the east coast of Brazil. After 12 days at sea the ship would sail past the majestic Sugarloaf and into the bay at Rio de Janiero.

Santos, the second port of call in Brazil, held a special place in Delta’s post-war cargo trade.  It was the world’s leading coffee loading port and American consumption of the aromatic bean had made Delta Line the globe’s largest coffee carrier – so much so in fact that Delta ships were known as the “Coffee Fleet”.  After Santos the ship sailed on to Montevideo, Paranagua and finally its destination of Buenos Aires.

Life on board these vessels was a pleasant surprise to passengers who had undertaken pre-war voyages in less refined ships.  Most appreciated was the air-conditioning, particularly after reaching some of the South American ports, but also appreciated was the swimming pool situated aft of the main superstructure on each liner.  These facilities, together with the open sun deck and nearby bar and cafe, assured a first class holiday for passengers as the ship sped southward.

At Buenos Aires the liners turned around for the three week voyage that would take them back to New Orleans.

The Final Years (1967 – 1972):
For twenty years the three light grey-hulled vessels carried a steady following of passengers – including the rich and famous – but economic difficulties were on the horizon.  By 1967 rising operating costs had exceeded passenger profits and the line was forced to discontinue its passenger trade, a service not to be renewed for another decade.  The DEL SUD, DEL MAR and DEL NORTE were converted over to express cargo liners supplementing an already growing fleet of Delta ships serving both coastlines of the South Atlantic and the Caribbean.

In early 1972 the three ships, now 25 years of age, were placed on a one-way charter run to Indonesia, one that eventually took them on to scrapping in Taiwan.  They had served a useful and profitable life – just missing, in fact, the dramatic rise in fuel prices during 1973 that would send many a newer ship out of business.  When it came time for Del Norte, the first of her class to be completed, to make her final departure from New Orleans she seemed reluctant to leave. Twice the ship swung back snug to the wharf before the efforts of river tugs, pilot and captain eased her out into the river for the final voyage to the scrappers.

Crowley tried to modernize the fleet, but decided to cut its losses by selling Delta to United States Lines in 1985, which subsumed Delta’s ships into its own fleet before going bankrupt in 1986.

Their passenger service, last under the American flag, was deluxe and first class cargo-passenger service.

  1. My father was working on the Del Mar as a New Orleans based S.I.U. electrician the day I was born in ’57. Dad retired as Chief Engineer working for Lykes Bros. S.S. Co.

  2. I so enjoyed these …. My grandfather is Captain Warren E. Wyman. We lost most of his sailing photos and other mementos in Hurricane Katrina. We are sitting here reminiscing as I write. ONE HAPPY GIRL!!! Anyone with any pics or memories of my Granddad, I’d greatly appreciate your forwarding them to me:

  3. Great Company to work for. Crewed the SS Del Alba as a deckhand in 1965.

  4. willard grainger

    Those were the days of really good service and loads of fun!! Our family traveled several times in the sixties
    New Orleans-Rio route stopping in Houston and St. Thomas.

  5. We returned from Rio de Janeiro, Brazil on the Del Mar in 1965. Certainly one of the most memorable experiences of my life. My parents, my sisters, and my brother and I enjoyed the 17 days at sea tremendously. Now a bygone era, there was nothing but first class everywhere you went. The only negative experience I had was being denied admittance to the dining room for dinner because I was not wearing a tie. I was a mere 12 years old at the time. Apart from that, it all seems like a wonderful dream now. Would that everyone on the planet could enjoy something so nice.
