I meanwhile tried to get to 32 kn. However, it's too big. I don't want to spent more than 7 BP. Ideas?

   Metacentric height 2,7 ft / 0,8 m
   Roll period: 14,3 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0,33
   Seaboat quality  (Average = 1.00): 1,00

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,504
   Length to Beam Ratio: 9,76 : 1
   'Natural speed' for length: 23,34 kts
   Power going to wave formation at top speed: 59 %
   Trim (Max stability = 0, Max steadiness = 100): 70
   Bow angle (Positive = bow angles forward): 0,00 degrees
   Stern overhang: 0,00 ft / 0,00 m

      - Stern:      16,40 ft / 5,00 m
      - Average freeboard:   18,24 ft / 5,56 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 119,3%
      - Above water (accommodation/working, high = better): 123,0%
   Waterplane Area: 20.313 Square feet or 1.887 Square metres
   Displacement factor (Displacement / loading): 110%
   Structure weight / hull surface area: 92 lbs/sq ft or 447 Kg/sq metre

Cut range and seakeeping. That extra knot costs like 700t.
