🔍 Key Concepts

• Twin-screw vs single-screw maneuverability and control if one engine/shaft is lost • How bollard pull (pulling power) relates to total horsepower and number/size of propellers • Effects of having two propellers on exposure to damage from debris

💭 Think About

• Think about whether simply adding a second screw automatically increases bollard pull if total horsepower stays the same. • Ask yourself: does having two propellers in the water make you more or less likely to suffer damage from floating debris? Why? • Consider what happens to control of the tug and tow if you lose one engine on a twin-screw boat compared to losing the only engine on a single-screw boat.

✅ Before You Answer

• Verify how bollard pull is usually determined for a tug (total horsepower, propeller design, and thrust efficiency). • Check which statements are clear advantages of twin-screw tugs that are commonly accepted in practice. • Identify the choice that makes a claim about performance that is not automatically guaranteed just because the tug has two screws.

Question 1 of 20

When comparing twin screw tug to single-screw tugs, which statement about a twin-screw tug is FALSE?

If one engine fails, you do not lose control of the tow.

It develops more bollard pull for the same horsepower.

It is generally subject to more propeller damage from debris in the water.

It is more maneuverable.
