I should be able to do better, I keep thinking. I was only able to achieve 35 knots, rather than 36 knots that I had hoped. This is with 52.395 SHP/ton machinery. Remember that with 1907 technology, the British Swift was able to produce 60 SHP/ton. The 52.395 should be reasonable, given that the British were able to do this with a similar ship. The main difficulty is that Springsharp requires too much power for the speed. This is the Springsharp report:
