To make a 1905 to 1907 destroyer "work" (and probably later)

I was just experimenting with an early Tribal class ship from about 1906 in Springsharp. To make it "work", I reduced the cruising speed to 12 knots and the fuel carried. The fuel turned out to be not necessary, as the reduction to 12 knots was the factor that was critical. Again, this is a design that has a composite strength less than 1.0 (0.54), and it still gets the accolade: "Design well balanced for a light fast combatant". The speed is 32 knots and the armament is 2-4in QF and 2-18in TT. By the way, I understand that the British 18in torpedo was actually the same diameter as the German torpedo (450mm), and the British just rounded the number to keep the terminology simple. The normal load displacement came out as 1,089 tons. The standard displacement was 1,013 tons. The usual issue with Springsharp 2.1 came into play: machinery for small vessels is too heavy and to great in volume for what was actually true. I would expect that to be reduced as in issue by Springsharp 3.0.
