🔍 Key Concepts

• Stability and center of gravity when additional weight is added high on the vessel • How ice forms and where it tends to accumulate on a ship at sea • Difference between trim, displacement, and stability

💭 Think About

• Think about where ice usually builds up on a vessel and whether that weight is high or low relative to the waterline. • Ask yourself which ship characteristic (trim, displacement, radar performance, or stability) is most directly affected by adding a lot of weight high above the vessel’s center of gravity. • Consider which change could most quickly threaten the vessel’s safety and risk capsizing in heavy weather.

✅ Before You Answer

• Be clear on the definition of stability versus trim—they are not the same thing. • Recall what happens to a vessel’s center of gravity (G) when weight is added high up, such as on masts, rigging, and superstructure. • Verify which of the listed effects would most seriously endanger the ship and crew, not just reduce efficiency.
