🔍 Key Concepts

• Twin-screw vs single-screw maneuvering (how two propellers affect control) • Side force / transverse thrust from propellers when going ahead or astern • How opposed propeller rotation can change turning and handling characteristics

💭 Think About

• Think about what happens if you put one engine ahead and the other astern—what special control or effect does that give you that a single-screw vessel cannot duplicate? • Which option describes something you can directly control or improve simply by having two separate propellers that can turn independently? • Ask yourself: does having two screws automatically change trim, speed, or resistance, or does it mainly change how the vessel can be handled?

✅ Before You Answer

• Check which choice refers to a maneuvering advantage rather than a performance claim like speed or trim • Verify whether side forces from twin screws truly cancel in all operating conditions, or only under specific arrangements • Question whether drag effect disappears just because there are two screws, or if total underwater resistance still exists in some form
