Today I noticed something strange - that ships Edmund Fitzgerald have steam engine. It seems quite strange - when their intro year is 1958. And it is strange mostly in comparison with else ships, for example Patagonia, that have earlier intro year and have diesel engine.
I know (or at least I think it) that engine type in case oif ships is quite irrelevant but it is very strange.
The SS Edmund Fitzgerald was a Great Lakes freighter originally build with coal-fired boilers, thus the steam engine (see here (http://en.wikipedia.org/wiki/Edmund_Fitzgerald)). Later on, in 1972 her boilers were refitted to burn oil instead.
The strange thing about the engines and dates could be because of the different ship types; maybe the ships at Great Lakes had some differences with the ships built to sail thru the oceans.
Thanks. Then it is OK.
