Bouclier Class Destroyer, laid down 1910
     Length, 80.0 m x Beam, 7.5 m x Depth, 4.0 m
          968 tonnes normal displacement (861 tonnes standard)
     Main battery:       2 x 10.0-cm (2 x 1)
     Secondary battery:  6 x  6.5-cm
     QF battery:         2 x  4.5-cm
     Light battery:      6 x  1.3-cm
          Weight of broadside: 53 kg
     4 TT, 45.0 cm
     Hull unarmored
     Maximum speed for 15832 shaft kw = 30.00 knots
          Approximate cruising radius, 3500 nm / 10 knots
     Typical complement: 87-113

                    Estimated cost, $454,000 (£114,000)
          Remarks:
     Caution: Hull structure is subject to strain in open-sea
     conditions.
     Good seaboat; rides out heavy weather easily.
     Magazines and engineering spaces are cramped, with poor
     watertight subdivision.
     Cramped ship; poor crew accommodation, limited working space.

          Distribution of weights:
                                                       Percent
                                                       normal
                                                    displacement:
          Armament .........................     15 tonnes =   2 pct
          Machinery ........................    515 tonnes =  53 pct
          Hull and fittings; equipment .....    242 tonnes =  25 pct
          Fuel, ammunition, stores .........    136 tonnes =  14 pct
          Miscellaneous weights ............     60 tonnes =   6 pct
                                              -----
                                                968 tonnes = 100 pct
          Estimated metacentric height, 0.2 m
     Displacement summary:
          Light ship:               832 tonnes
          Standard displacement:    861 tonnes
          Normal service:           968 tonnes
          Full load:               1050 tonnes
          Loading submergence 327 tonnes/metre

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.13
          Shellfire needed to sink: 87 kg = 6.3 x 10.0-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)
          Torpedoes needed to sink: 0.2
               (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, 0.67
          Relative quality as a seaboat: 1.22

     Hull form characteristics:
          Block coefficient: 0.40
          Sharpness coefficient: 0.29
          Hull speed coefficient 'M' = 8.11
          'Natural speed' for length = 16.2 knots
          Power going to wave formation
               at top speed: 67 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 190 percent
          Relative accommodation and working space: 68 percent

          Displacement factor: 46 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 0.51
               (Structure weight per square
               metre of hull surface: 142 kg)
          Relative longitudinal hull strength: 1.96
               (for 3.90 m average freeboard;
               freeboard adjustment +1.01 m)
          Relative composite hull strength: 0.58
