What is the maximum angle of heel allowed on passenger ships due to passengers as per the current IMO Intact Stability Code?

• A. 15 degrees
• B. 20 degrees
• C. 10 degrees
• D. 5 degrees

Answer: (C)

The maximum angle of heel allowed on passenger ships, according to the current International Maritime Organization (IMO) Intact Stability Code, is indeed 10 degrees. This regulation ensures the ship maintains adequate stability under various conditions, particularly when accommodating passengers who may be moving about or experiencing motion due to the ship's movement.

Allowing a heel of more than 10 degrees can pose a safety risk. Passengers could be at risk of injury in higher heel angles, as it may hamper their ability to move safely within the vessel. Therefore, the code emphasizes maintaining a stable environment where the heel does not exceed this limit, ensuring passenger safety and comfort aboard. This limit helps in managing both the general stability of the vessel and the safety of those on board, thus reinforcing the importance of adhering to the specific angle of heel prescribed by the Intact Stability Code.
