The main force that opposes a ship's forward motion is called:

• Lift

• Thrust

• Drag

• Gravity

The deadweight of a ship refers to the:

• Empty weight of the ship

• Total weight the ship can carry

• Weight of the fuel

• Weight of the crew and passengers

The part of a ship that cuts through the water is called the:

• Stern

• Bow

• Deck

• Keel

The vertical distance between the waterline and the keel is called the:

• Draft

• Freeboard

• Beam

• Length

The transverse watertight compartments within a ship are called:

• Frames

• Bulkheads

• Keel

• Stringers

The international organization that sets safety standards for ships is called:

• Federal Aviation Administration (FAA)

• International Maritime Organization (IMO)

• National Aeronautics and Space Administration (NASA)

• International Civil Aviation Organization (ICAO)

Catamarans are multihull vessels known for their:

• High speed

• Deep draft

• Heavy cargo capacity

• Excellent stability

Bulbous bows are design features that aim to:

• Increase cargo space

• Reduce wave resistance

• Enhance maneuverability

• Improve passenger comfort

Finite element analysis (FEA) is a computational tool used for:

• Route optimization

• Hull stress analysis

• Crew scheduling

• Weather prediction

What is the purpose of a ship's keel?

• To increase cargo space

• To reduce wave resistance

• To enhance maneuverability

• To provide stability
