🔍 Key Concepts

• Review the difference between hogging and sagging bending moments and how the hull is curved in each case. • Think about how adding or removing weight at different longitudinal positions (ends vs amidships) changes the bending moment curve. • Relate the blue arrows in the illustration to weight (downward) and buoyancy (upward) forces along the ship’s length.

💭 Think About

• In a hogging condition, is the middle of the ship higher or lower than the bow and stern? Visualize how the hull is bent. • If the ship is already hogging, would putting more weight at the ends increase or decrease that upward bend in the middle? What about putting more weight in the middle? • Which ballast action would tend to counteract the bending shape you see in the illustration, rather than exaggerate it?

✅ Before You Answer

• Be clear on which part of the ship (ends or amidships) is under greater upward force in a hogging condition. • Decide whether you want to increase weight amidships or increase weight at the ends to straighten a hogging hull. • Check that your chosen option would reduce the existing bending (make the hull closer to straight), not simply shift the problem elsewhere.
