What is the maximum angle of heel allowed after flooding for Type A and Type B vessels?

The maximum angle of heel allowed after flooding for Type A and Type B vessels is 15 degrees. This standard is critical for maintaining the stability of the vessel in the event of flooding, which can occur due to damage to the hull or other unforeseen circumstances.

Type A and Type B vessels, which are categorized based on their construction and intended use, must adhere to safety regulations that ensure they can remain upright and operable even under distressing conditions such as flooding. A heel of more than 15 degrees could compromise the vessel's stability, potentially leading to capsizing.

The requirement for a maximum heel angle of 15 degrees reflects a balance between safety and operational capability, ensuring that vessels can handle adverse conditions while still being able to navigate effectively. This regulation helps to protect both the crew and the vessel during an emergency situation.
