Moment of statical stability = W GZ
At small angles of heel:
By wall-sided formula:
By Attwood s formula:
Stability curves:
W = ship displacement in tonnes
GG H = horiz movement of G
GG V = vert movement of G
? o = righting arm @ ? = 0 (if upright ship)
? 40 = righting arm @ ? = 40 Z
HM = heeling moment
SF = stowage factor
VHM = volumetric heeling moment
Increase in draft due to list:
New draft = 1/2 b sin ? + (d) cos ? Rise of floor is zero put r in if rise of floor exists. (measured at full Br. Mld)
Inclining experiment:
