In these days when most things are observed superficially this is a fantastic introduction into the ship construction and operation in the 1910's, and an insight into early C20 heavy engineering and methods. I stress introduction, as it does not labour any aspect to boredom, it whets the appetite, in fact some areas could do with more detail (see Johnathan Smith's critique below) There are so many things I had never heard before, the third shaft was turbine driven by exhaust steam, a steam reciprocating fridge plant and how to bend a ships frame - and so on. I showed it to both the Chief Engineers and Officers on my ship and they were all amazed by it. Very enjoyable and J. Smith is right, for more follow his lead, but read this one first. It was also a good reminder of our lost heritage in heavy manufacturing of which we were once the lead (S. Korea delivers a ship - ocean going-every two days out of three all year!!) GREAT FUN, loved it.
