I just calculated the power curve for my "Compact Large Battleship"

Now that I am confident that my power calculation program is working, I tried it out on the "Compact Large Battleship". The specs are:
  • displacement: 85,484.2 tons
  • dimensions: 900ft x 150ft x 35.7ft
  • Cp: 0.64
  • Cm: 0.97

I ran a curve from 10 knots to 23 knots:

  • 10 knots: 6,124.24 SHP
  • 11 knots: 7,904.5 SHP
  • 12 knots: 9,995.1 SHP
  • 13 knots: 12,408.4 SHP
  • 14 knots: 15,182.8 SHP
  • 15 knots: (found a bug at this point: SLR 0.5)
  • 16 knots: 27,082.1 SHP
  • 17 knots: 36,911.9 SHP
  • 18 knots: 47,839.7 SHP
  • 19 knots: 60,018.2 SHP
  • 20 knots: 73,454.9 SHP
  • 21 knots: 88,066.5 SHP
  • 22 knots: 103,897.0 SHP
  • 23 knots: 120,946.0 SHP

Obviously, I have a bug that happens Speed-Length Ratios that are exact multiples of 0.5.
