Mediniy Class Motor Torpedo Boat, laid down 1916
     Length, 30.0 m x Beam, 6.0 m x Depth, 2.6 m
          99 tonnes normal displacement (98 tonnes standard)
     Main battery:       2 x  3.7-cm
     Light battery:      4 x  1.3-cm
          Weight of broadside: 2 kg
     2 TT, 45.0 cm
     Hull unarmored
     Maximum speed for 3579 shaft kw = 26.00 knots
          Approximate cruising radius, 300 nm / 10 knots
     Typical complement: 16-20

                    Estimated cost, $77,000 (19,000)
          Remarks:
     Caution: Hull structure is subject to strain in open-sea
     conditions.
     Caution: Delicate, lightwight machinery.
     Caution: Very cramped ship with excessively poor habitability;
     lacks suitable working space.
     Oil firing.
     Ship has slow, easy roll; a good, steady gun platform.
     Good seaboat; rides out heavy weather easily.
     Magazines and engineering spaces are cramped, with poor
     watertight subdivision.

          Distribution of weights:
                                                       Percent
                                                       normal
                                                    displacement:
          Machinery ........................     57 tonnes =  58 pct
          Hull and fittings; equipment .....     38 tonnes =  38 pct
          Fuel, ammunition, stores .........      4 tonnes =   4 pct
          Miscellaneous weights ............      0 tonnes =   0 pct
                                              -----
                                                 99 tonnes = 100 pct
          Estimated metacentric height, 0.1 m
     Displacement summary:
          Light ship:                95 tonnes
          Standard displacement:     98 tonnes
          Normal service:            99 tonnes
          Full load:                100 tonnes
          Loading submergence 64 tonnes/metre
     +++++++++++++++++++++++++

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.04
          Shellfire needed to sink: 10 kg = 14.9 x 3.7-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)
          Torpedoes needed to sink: 0.1
               (Approximates number of 'typical'
               torpedo hits needed to sink ship)
          Relative steadiness as gun platform, 70 percent
               (50 percent is 'average')
          Relative rocking effect from firing to beam, 0.04
          Relative quality as a seaboat: 1.20
     +++++++++++++++++++++++++

     Hull form characteristics:
          Block coefficient: 0.21
          Sharpness coefficient: 0.27
          Hull speed coefficient 'M' = 6.49
          'Natural speed' for length = 9.9 knots
          Power going to wave formation
               at top speed: 79 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 190 percent
          Relative accommodation and working space: 47 percent

          Displacement factor: 27 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 0.35
               (Structure weight per square
               metre of hull surface: 86 kg)
          Relative longitudinal hull strength: 13.42
               (for 3.55 m average freeboard;
               freeboard adjustment +1.72 m)
          Relative composite hull strength: 0.50
