FAQ: When Were The New Suites Forward on B-deck Added to Olympic?

Although it is popularly believed that they were added in 1928, at the same time as changes were made to second and tourist class areas, in fact there was not a single, major refit in 1928. Instead, some changes were made over the winter of 1927-28, and some over 1928-29. The new suites were added over the winter of 1928-29. By 1929, B-deck had become A-deck, however the original deck designation from 1911 is being used because readers will be more familiar with it. (See: ‘RMS Olympic: The Mis-dated Refit’.) 

 


 

FAQ: How Much Did Titanic Weigh?

FAQ: Titanic‘s Weight: How Much Did Titanic Weigh?

Gross tonnage is NOT a measure of weight

There is a lot of confusion about the subject of Titanic‘s weight, which is not helped by some of the terminology used.  We often see references to the ship’s ‘gross tonnage’.  However, despite what the term implies with the use of the word ‘tonnage’, it is not a measure of weight.  It actually measures the total enclosed space within the ship’s hull and superstructure. Therefore references in the media which refer to a comparison of ‘gross tonnage’ and to Titanic being approximately 1,000 tons ‘heavier’ than her sister Olympic are completely inaccurate (and all too common).

The total weight of the ship (displacement) was calculated as 52,310 tons when she was loaded to her designed draught of 34 feet 7 inches – precisely the same as her sister Olympic.  (Their larger, younger sister ship Britannic had a displacement of 53,170 tons and the same designed draught.)  This was made up of the lightweight (the weight of the ship herself, including her hull, engines, machinery and permanent fittings before she was loaded for sea) plus the deadweight (the weight of the cargo loaded onboard, including everything from her human cargo – passengers and crew – to the coal, other supplies for the voyage and commercial cargo carried in the ship’s holds).  These figures are all given in the British, Imperial measure.

This data is taken from shipbuilder Harland & Wolff’s records and summarised below.  We see that Titanic in an unloaded condition weighed 480 tons more than her older sister Olympic and that her deadweight was correspondingly smaller. However, both ships’ total weight (displacement) was the same assuming that they were loaded to their designed draught.   

 

It is important to understand that, despite all the confusion in secondary sources (such as articles, books, television programmes and so forth), the primary source evidence (original, contemporary documentation) is all very clear in regard to how much the ship weighed.  The ship’s displacement is confirmed in multiple original documents, including Harland & Wolff’s records; Olympic‘s displacement scale (which shows how much water she displaced at a given draught); and the Board of Trade.  It is benchmarked against figures Thomas Andrews provided for Olympic in 1911.
