Czas na pierwszą serię torpedowców. Zgodnie z tendencjami
panującymi we flotach na przełomie lat 70-tych i 80-tych XIX w., są to okręty
małe, jak na swój czas dość szybkie, ale o ograniczonej wartości bojowej, ze
względu na całkowitą w zasadzie zależność warunków pogodowych – prowadzenie
przez nie działań jest możliwe w zasadzie tylko przy minimalnych falach. W
dodatku, nikły zasięg ogranicza możliwość ich użycia do działań typowo
przybrzeżnych. Typ liczy sobie 4 jednostki, tworzących pierwszy dywizjon torpedowców
w naszej flocie.

Cost:
£0,005 million / $0,019 million
Distribution of weights at normal displacement:
Armament: 0 tons, 0,0%
Machinery: 26 tons, 69,3%
Hull, fittings & equipment: 7 tons, 20,0%
Fuel, ammunition & stores: 3 tons, 8,0%
Miscellaneous weights: 1 tons, 2,7%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
3 lbs / 2 Kg = 0,0 x 6 " / 152 mm shells or 0,0 torpedoes
Stability (Unstable if below 1.00): 1,27
Metacentric height 0,2 ft / 0,1 m
Roll period: 8,4 seconds
Steadiness - As gun platform (Average = 50 %): 6 %
- Recoil effect (Restricted arc if above 1.00): 0,00
Seaboat quality (Average = 1.00): 0,01
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,541
Length to Beam Ratio: 6,86 : 1
'Natural speed' for length: 8,11 kts
Power going to wave formation at top speed: 85 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -31,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 2,49 ft / 0,76 m
- Forecastle (20%): 2,99 ft / 0,91 m
- Mid (50%): 2,99 ft / 0,91 m
- Quarterdeck (15%): 2,49 ft / 0,76 m
- Stern: 2,00 ft / 0,61 m
- Average freeboard: 2,75 ft / 0,84 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 226,2%
- Above water (accommodation/working, high = better): 16,9%
Waterplane Area: 422 Square feet or 39 Square metres
Displacement factor (Displacement / loading): 6%
Structure weight / hull surface area: 11 lbs/sq ft or 52 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,47
- Longitudinal: 1,34
- Overall: 0,52
Caution: Hull subject to strain in open-sea
Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is extremely poor
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability

W każdym razie trzeba od czegoś zacząć.
