Q

When a wind force causes a floating MODU to heel to a static angle, the __________.

🔍 Key Concepts

• Static angle of heel vs. angle of loll • Relationship between righting moment and heeling moment in equilibrium • How center of gravity (G) and center of buoyancy (B) line up at different stages of heel

💭 Think About

• At a steady, unchanging heel (not rolling), what must be true about the balance of forces and moments? • Does deck-edge immersion or downflooding always happen at the first static angle of heel from wind, or only beyond certain angles? • In normal positive stability, are G and B exactly in the same vertical line when the vessel is heeled and stable, or only under a very specific condition?

✅ Before You Answer

• Verify what equilibrium of moments means for a vessel at a constant heel angle • Think about when the GZ (righting arm) becomes zero and how that relates to G and B being vertically aligned • Consider whether deck edge immersion or downflooding are guaranteed at small to moderate steady heel angles, or if they depend on hull shape and freeboard
