Within this forward region lies a critical feature: the prow. What Is the Prow of […]
Margin Lines in Naval Architecture
Introduction: Damage Stability and Safety Margins In naval architecture, damage stability is one of the most important considerations in vessel design. It deals with the ways a ship might sink or lose stability if physical damage causes water ingress into watertight spaces. Two primary methods exist for assessing damage stability: Since 2009, all dry cargo […]
