WebIn lesson 4.01 the relationship between Metacentric Height (GM) and righting arms (GZ) was discussed. For small angles of heel (0°-7/10°) GZ is proportional to GM. Therefore, GM can be used as a representation of initial righting arms. These basic rules apply: If GM is large, the ship has large righting arms and will have stiff, fast rolls. WebIt will be noticed that at the angle of loll, the GZ is zero. G remains on the centerline. If the ship is heeled beyond the angle of loll from θ1 to θ2, the center of buoyancy will move out still further to the low side and there will be a moment to return her to the angle of loll, as shown in Figure 2.5 (c).

WebFeb 19, 2024 · Therefore the dynamical stability from 9 to (9 + d9) is W X (GZ X d9). Refer now to Figure 22.2(c) which is the curve of statical stability for the ship. At 9 the ordinate is GZ. The area of the strip is GZ X d9. But W X (GZ X d9) gives the dynamical stability from 9 to (9+d9), and this must be true for all small additions of inclination. WebThe righting lever (GZ) shall be at least 0.20 meters at an angle of heel equal to or greater than 30°. From: Ship Stability for Masters and Mates (Seventh Edition), 2012.
