Ahoy,
This is what "Merchant Ships 1956" says:
REINA DE MAR,20,225 tons gross.This new passenger liner, built for the PSNC by Harland & Wolff Ltd.,Belfast,has joined the REINA DEL PACIFICO to maintain the service from the UK,France and Spain to Bermuda,the Bahamas,Cuba,Jamaica,Panama,Colombia,Ecuador,Peru and Chili, and augmented service enables calls at Trinidad and in Venezuela to be added. The REINA DEL MAR ia a twin-screw turbine ship with a lenght o.a 600 ft. 7in,lenght b.p. 560 ft.,breadth moulded 78 ft.,depth moulded to C deck 44 ft,draught 30 ft. In appearence the ship is graceful and has the modern tapered funnel for keeping the smoke clear of the decks. The hull is largely riveted,though butts are welded, and welding has been extensively used inside the ship.
In common with ther new passenger vessels she is fitted with Denny-Brown stabilizers. The propelling machinery consists of a two-shaft arrangement of Parson' double-reduction geared turbines,having a total power in service of 17,000 s.h.p,with propeller revolutions of 112 per minute. Stean at 525lb per sq. in. pressure and 825 degree F. temperature is generated in two water boiler made by the builders to Babcock & Wilcox controlled-superheat three-drum design, The REINA DEL MAR does not reflect the modern tendency towards a one- or two class ship, as she is desigbed for the South American trade where there remains a demand for the conventional three classes. Well-to-do South Americans expect and are prepared to pay for the best possible accommodation and service, and the ship provides for 207 first class passengers. I n the cabin class there is accommodation for 216 passengers in single, tw, three, four-berth rooms. The 343 tourist class passengers are provided for in cabins with one to six berths, and consist largely of emigrants when first leavinf Europe and other returning to re-visit it. A feature of this modern three-class ship is that in effect there is a move up for all three classes,the first class becoming "de luxe", the second class becoming first. and the third class is better than the second class accommodation in older ships. Air condition covers the whole of the passenger accommodation. In addition to passenger accommodation the REINA DEL MAR has a total of 6,000 tons for cargo in five holds. The outward cargo is mostly of manufacturers' goods, but much of the homeward cargo consists of heavy commodities such as metal ores. There are insulated cargo spaces in No. 4 tunnel and lower tweendecks.
