🔍 Key Concepts

• Turning circle of a vessel and its key parts (advance, transfer, tactical diameter) • Movement of the vessel measured along the original course line vs at right angles to it • What happens immediately after the rudder is put over and the vessel begins to swing

💭 Think About

• Picture a ship on a straight course that suddenly puts the rudder hard over. As it begins to turn, how far does it continue to move forward along its original course line before it is well into the turn? • Which term in ship-handling describes how much of the ship’s motion is still in the original direction during the initial part of the turn, before the heading has changed a lot? • Look at which choices describe sideways motion versus forward motion. Which term “advance” most likely refers to in normal English and in ship-handling context?

✅ Before You Answer

• Identify which option talks about distance measured in the direction of the original course, not sideways to it • Separate terms that describe sideways (at right angles) movement from those that describe forward movement • Remember that the turning circle terminology uses different words for motion ahead versus motion to the side; make sure you match “advance” to the correct axis of motion
