Residual GM Check

Quick check of residual metacentric height after damage - SOLAS II-1 Reg 8 requires GM ≥ 0.05 m final.

Formula, assumptions, and limits

Simplified - the full assessment integrates the GZ curve from 0° to downflooding angle to verify residual range ≥ 7° (passenger) / ≥ 15° (cargo) and residual GZ_max ≥ 0.1 m. Use this as a first-look check.
