It represented a discontinuity of about 40 years. Afterwards, competition between liner companies (and later cruises) kept a discontinuity from arising, though ship size kept increasing. + +Two difficulties arise: Firstly, the most convenient data only includes passenger ships. However, both categories were synonymous in the period of interest: passenger ships were routinely the biggest ships at least until WW1 (S President, the SS British Queen, SS Great Eastern, the RMS Celtic, RMS Baltic, the RMS Titanic, etc). Nonetheless, at some point afterwards, other categories of ship, i.e., oil tankers become the biggest ships overall. R.C. Anderson's *Big Ships in History* serves as a sanity check on this. Secondly, the sizes of the ships of antiquity are not well recorded. For this reason, I just consider data for European ships, starting in the 19th century, and exclude f.ex., Chinese, Greek and Javanese naval history. I feel that this makes sense, because the [Thalamegos's](https://en.wikipedia.org/wiki/Thalamegos) (200 BCE) size of 115 meters just wasn't surpassed by anything in Europe until the SS Great Eastern itself, although perhaps by poorly documented [Chinese](https://en.wikipedia.org/wiki/Louchuan) and [Javanese](https://en.wikipedia.org/wiki/Djong_(ship)#Decline) ships. + +Here follow four images which make the discontinuity apparent. In the later two, the already mentioned Thalamegos and the Syracusia (designed by Archimedes) are given as reference points. + +![](https://nunosempere.github.io/rat/SS-Great%20Eastern-3.png) +![](https://nunosempere.github.io/rat/SS-Great%20Eastern-4.png) +![](https://nunosempere.github.io/rat/SS-Great%20Eastern-1.png) +![](https://nunosempere.github.io/rat/SS-Great%20Eastern-2.png)
