By giving a little on protection, 37 knots is possible

This is a slight revision to the extreme version of the GB/CB/1907 so that 37 knots can be achieved. A modest reduction in protection makes it possible, along with slightly higher output machinery.

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   27,785 lbs / 12,603 Kg = 32.2 x 12.0 " / 305 mm shells or 3.0 torpedoes
