Q

When backing down with sternway, where will the pivot point of a vessel be located?

🔍 Key Concepts

• Pivot point behavior when moving ahead vs. astern • How water flow along the hull changes when a ship has sternway • Typical positions of the pivot point as a fraction of ship’s length from bow or stern

💭 Think About

• First picture where the pivot point is when a ship is moving ahead at steady speed. Now, when you reverse and build up sternway, does the pivot point move toward the bow or toward the stern? • Compare the choices: are they placing the pivot point near the bow, near the stern, or somewhere in between? Which matches what happens when the stern is the leading end? • Think about which end of the ship now has the greatest water flow and control forces (rudder, propeller wash when applicable). The pivot point usually shifts toward that end.

✅ Before You Answer

• Be clear that the question is about a vessel with sternway (steady astern motion), not just a momentary kick astern from a stop • Focus on where the effective “leading end” of the hull is when backing—this is where the pivot point tends to move • Check which answer puts the pivot point at a realistic fraction of the length from the leading end when moving astern (about a quarter to a third of the length, not right at the extreme end)
