A vessel reduces speed without backing. Which item is the primary factor that determines the rate that her speed through the water decreases?

🔍 Key Concepts

• The difference between displacement and horsepower • How resistance in the water relates to a ship’s size and underwater volume • What changes when you reduce power ahead but do NOT go astern

💭 Think About

• If engines are brought to neutral (no backing), what physical characteristic of the ship most affects how long it ‘coasts’ through the water? • Would a larger, heavier ship slow down faster or slower than a smaller, lighter one, assuming similar conditions? Why? • Which options are about the ship’s inherent mass/volume, and which are about machinery or environment that mainly affect acceleration rather than passive slowing?

✅ Before You Answer

• Identify which choice describes the ship’s mass/weight in the water rather than its machinery • Consider which factor continues to matter even if the engine is not producing thrust • Ask: if two ships have the same power but very different size and weight, will they lose speed at the same rate when you stop powering ahead?
