My 2001 version of the GB/DD/1906 destroyer

When I just entered my GB/DD/1906 design into Springsharp, I used 18in torpedo tubes, as I couldn't stand to do what my friend Cliff had done, and give them 21in TT in 1906. I also increased the draft to 11ft and used a normal displacement of 965 tons. The freeboard is also a bit high, to achieve adequate seakeeping ability. The dimensions are 265ft x 26ft x 11ft. The armament is 2-4in QF guns and 2-18in TT. The speed is my standard 32 knots. This is the Springsharp report:
