Damage Stability - Margin-Line Clearance
Margin-line clearance check - in damaged condition, the waterline must not immerse the margin line (76 mm below bulkhead deck at side) per SOLAS II-1 Reg. 7.
Margin line clearance
0.099m
Result
Pass - margin line not immersed
Formula, assumptions, and limits
Classic deterministic criterion (SOLAS II-1 Reg. 7-2 for pre-2009 ships). Probabilistic method (Part B-1) replaced it for new builds but margin line retains engineering significance.
