Inclining Experiment - GM from Pendulum
GM result from an inclining experiment - weight shift × arm / (displacement × tan θ). Mandatory verification for new-build / major modification per SOLAS II-1 Reg. 5.
Heel angle
0.764deg
GM (fluid)
1.875m
Formula, assumptions, and limits
Inclining weights must produce deflection in 1–4° range. Ship must be upright and moored loosely. Result compared against predicted GM from stability booklet lightship KG.
