1 / 6

Which of the following conditions is most likely to increase the occurrence of racking?

B) The vessel moving through rough seas with significant rolling motion

C) The vessel being drydocked for repairs

D) The vessel anchored in port

A) The vessel at rest in calm water

2 / 6

What is the meaning of the term "racking" as it applies to a vessel’s hull?

D) The corrosion of the hull due to saltwater

C) The forward movement of the vessel under propulsion

A) The vertical movement of the hull due to waves

B) The side-to-side distortion of the ship’s hull caused by external forces

3 / 6

Which structures in a vessel help resist racking?

C) Transverse bulkheads and side frames

A) The propeller and rudder assembly

B) The ship’s engines and boiler rooms

D) Lifeboats and davits

4 / 6

How does racking occur in a vessel’s hull?

C) Through the side-to-side force exerted on the hull by waves, causing distortion in the transverse bulkheads

D) By the temperature changes affecting the hull’s metal structure

B) Due to vertical pressure on the deck during calm conditions

A) By the longitudinal bending when the vessel is under heavy cargo load

5 / 6

What is the role of transverse bulkheads in preventing racking?

C) They divide the ship into compartments and add lateral strength to resist distortion

B) They provide vertical stability to prevent pitching

D) They assist with cargo loading operations

A) They help maintain buoyancy

6 / 6

Which additional structure complements transverse bulkheads to enhance resistance to racking?

C) Deckhouse supports

B) Longitudinal stringers

A) Keel blocks

D) Cargo hold partitions
