Dziś prezentuje pomocnicze stawiacze min. Są to oczywiście prowizorycznie
zaadaptowane stare statki handlowe, w których miny (w ilości 160 sztuk) zostały
rozmieszczone w ładowniach i są wynoszone na pokład za pomocą dźwigów
stanowiących oryginalne wyposażenie tych jednostek. Oprócz min okręty posiadają
na wyposażeniu po dwa stare działa kal. 57 mm zdjęte z wycofanych,
XIX-wiecznych jednostek bojowych. Jest to symboliczne uzbrojenie, ale uznałem,
że wystarczające, bowiem każda operacja jaką te jednostki będą przeprowadzać, w
założeniu ma się odbywać pod osłoną własnych okrętów wojennych „z prawdziwego
zdarzenia”, a poza tym, z natury rzeczy – w pobliżu własnych baz (są to
stawiacze min o zdecydowanie defensywnym charakterze, nie planuję wysyłania ich
pod nos nieprzyjaciela, mimo iż takie rzeczy w czasie wojny się zdarzały – vide
działalność niemieckiego pomocniczego stawiacza min Deutschland, który operował
nawet w pobliżu Zatoki Fińskiej).

Distribution of weights at normal displacement:
Armament: 1 tons, 0,1%
Machinery: 200 tons, 15,8%
Hull, fittings & equipment: 798 tons, 63,1%
Fuel, ammunition & stores: 146 tons, 11,6%
Miscellaneous weights: 120 tons, 9,5%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
2 075 lbs / 941 Kg = 367,2 x 2,2 " / 57 mm shells or 1,0 torpedoes
Stability (Unstable if below 1.00): 1,00
Metacentric height 0,8 ft / 0,2 m
Roll period: 13,9 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0,03
Seaboat quality (Average = 1.00): 2,00
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,587
Length to Beam Ratio: 6,85 : 1
'Natural speed' for length: 14,26 kts
Power going to wave formation at top speed: 44 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0,00 degrees
Stern overhang: 10,47 ft / 3,19 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 18,96 ft / 5,78 m
- Forecastle (14%): 12,96 ft / 3,95 m
- Mid (50%): 10,43 ft / 3,18 m
- Quarterdeck (9%): 11,45 ft / 3,49 m
- Stern: 11,98 ft / 3,65 m
- Average freeboard: 11,91 ft / 3,63 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 63,4%
- Above water (accommodation/working, high = better): 87,2%
Waterplane Area: 4 258 Square feet or 396 Square metres
Displacement factor (Displacement / loading): 239%
Structure weight / hull surface area: 100 lbs/sq ft or 486 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 2,11
- Longitudinal: 8,87
- Overall: 2,43
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
