🔍 Key Concepts

• Difference between horsepower and pulling force • Meaning of static vs. underway/cruise for a tug • How tug performance is tested against a fixed bollard or shore fitting

💭 Think About

• Ask yourself: Is bollard pull measured while the tug is moving at speed or while it is held in one place? • Which choice describes a force (pull) rather than just engine power or winch capacity? • Think about how a tug’s effectiveness in assisting ships in port is usually expressed and tested.

✅ Before You Answer

• Identify which options describe power vs. pulling force • Decide whether bollard pull is about dynamic (moving) or static (not moving) conditions • Rule out any options that refer only to engine rating or winch rating rather than the tug’s overall pulling capability
