Area II [GREATER THAN]Area I + K
Where-
HA = HAO cos (T)
Where-
HA = heeling arm.
HAO = heeling arm at 0 degrees of heel.
T = angle of heel.
Where-
GZ(1) is the righting arm curve at the displacement corresponding to the vessel without hooking load.
GZ(2) is the righting arm curve at the displacement corresponding to the vessel with hook load.
HA(1) is the heeling arm curve due to the combined heeling moments of the hook load and the counterballast at the displacement with hook load.
HA(2) is the heeling arm due to the counterballast at the displacement without hook load.
Theta(c) is the angle of static equilibrium due to the combined hook load and counterballast heeling moments.
Theta(f) is the downflooding angle on the counterballasted side of the vessel.
