Question 1 of 27070

A concentration of weight has been shifted inboard to the center line of the vessel. Generally speaking, what effect will this have on the vessel?

🔍 Key Concepts

• Transverse weight shift – shifting weight toward or away from the centerline • How weight distribution affects metacentric height (GM) and stability • Relationship between GM and a vessel’s rolling period (slow vs. quick roll)

💭 Think About

• When weight is moved inboard toward the centerline, does the vessel become more or less stiff (quick to right itself)? • If the vessel becomes more stable (larger GM), does the rolling period get longer (slower roll) or shorter (faster roll)? • Think about a small boat: when everyone moves to the middle instead of the rail, does it feel more or less ‘tippy,’ and how does that affect how quickly it rolls back upright?

✅ Before You Answer

• Recall that larger GM is associated with a stiffer, faster roll and smaller GM with a softer, slower roll • Connect: moving weight toward the centerline generally increases transverse stability (GM) • Match the description of the roll (faster vs. slower) with the choice that correctly describes change in rolling period (increase vs. decrease)
