Topic Ship Stability and Seakeeping Naval guide to ship stability and seakeeping: loading, metacentric height, righting arms, free-surface effects, roll response, wave encounter, testing, and simulation. Glossary term Ballast System Marine system that transfers, stores, and controls ballast water or ballast mass to manage draft, trim, stability, and operation. Glossary term Buoyancy Upward force exerted by a fluid on an immersed or floating body, governed by displaced fluid weight and pressure distribution. Glossary term Displacement Mass, weight, or volume relationship describing how much water a floating vessel or marine body displaces. Glossary term Freeboard Vertical distance from the waterline to a deck, opening, or reference height that indicates reserve buoyancy and flooding margin. Glossary term Metacentric Height Initial stability measure equal to the vertical distance between a vessel center of gravity and metacenter. Glossary term Mooring System Arrangement of lines, anchors, fittings, controls, and monitoring used to hold a vessel or floating offshore asset in position. Glossary term Righting Arm Lever arm between buoyancy and weight forces that creates a righting or overturning moment for a heeled floating body. Glossary term Seakeeping Ability of a vessel or floating system to operate safely and effectively in waves, wind, current, and real sea conditions. Glossary term Ship Draft Vertical distance from the waterline to a vessel reference point, used to manage loading, clearance, stability, and performance. Glossary term Ship Trim Difference between forward and aft draft that affects vessel hydrostatics, resistance, propulsion, steering, and operation. Formula sheet Marine Vessel Performance Formula Sheet Marine vessel formulas for buoyancy, displacement, draft, stability, resistance, power, propulsion, cavitation, scaling, pressure, stress, fatigue, and corrosion.
