Question 856 Deck General

The correct answer is D) Stuelcken boom. A Ro-Ro (Roll-on/Roll-off) vessel is designed to efficiently load and unload vehicles and other cargo that can be driven on and off the ship. The key loading and transfer features on a Ro-Ro vessel include cargo lifts, hatch openings designed as lifts, and stern and/or side ramps. However, a Stuelcken boom is not a standard loading or transfer feature on a Ro-Ro vessel, as it is more commonly used on general cargo ships to lift heavy or oversized items. The other answer choices are all characteristic of Ro-Ro vessel design and operations.
