Przygotowałem dwa wstępne warianty PKR 2A i PKR 2B. PKR 2A tj. wariant maximum - czyli okręt ma charakterystyki na wymaganym poziomie, kosztem zwiększenia wyporności, która wyniosła 16.161 ton std. Drugi wariant - PKR 2B, to wariant skrojony pod wymaganą wyporność, czyli 15.000 ton std. Okazało się, że nie trzeba w tym przypadku iść na jakieś wielkie kompromisy - ograniczenie prędkości do 33 w. (czyli de facto mocy, a zatem i masy siłowni) wystarczyło by zmieścić się w limicie.
Poniżej prezentuję raporty:

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,569
Length to Beam Ratio: 7,89 : 1
'Natural speed' for length: 24,35 kts
Power going to wave formation at top speed: 65 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 22,50 degrees
Stern overhang: 7,51 ft / 2,29 m
Freeboard (% = measuring location as a percentage of overall length):

- Stern: 19,75 ft / 6,02 m
- Average freeboard: 19,72 ft / 6,01 m
Ship tends to be wet forward
Ship space, strength and comments:

Waterplane Area: 31 655 Square feet or 2 941 Square metres
Displacement factor (Displacement / loading): 107%
Structure weight / hull surface area: 126 lbs/sq ft or 615 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,97

Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Caution: Lacks seaworthiness - very limited seakeeping ability
