Q

When underway and proceeding ahead, as the speed increases, what happens to the pivot point?

🔍 Key Concepts

• Pivot point location on a vessel when stopped vs. when making way • How water flow along the hull changes as speed increases • Relationship between turning lever arm (between pivot point and center of gravity) and ship handling

💭 Think About

• Think about where a ship tends to turn around when it is almost stopped compared to when it is moving ahead at normal sea speed. Does the bow or stern seem to swing more? • If the water flow along the hull becomes stronger as speed increases, which part of the hull (forward or aft) becomes more "locked in" and which part tends to swing out during a turn? • Imagine looking from above as the ship turns to starboard at higher speed: which end seems to trace the wider arc?

✅ Before You Answer

• Be clear on what "underway and proceeding ahead" means (not stopped, not astern, making headway through the water). • Recall the usual pivot point position at dead slow or stopped versus at full ahead for a displacement vessel. • Verify whether the bow or stern has the greater sideways movement when the rudder is applied at higher speed.
