How are the gripes typically released?

Gripes are the lines used to secure a lifeboat to the launching apparatus, and understanding how they are released is crucial for safe evacuation procedures. The correct answer indicates that gripes can be released both manually and automatically, which provides flexibility depending on the circumstances.

In emergency situations, such as during a lifeboat launch, it is essential that crew members can release the gripes quickly and efficiently. Manual release can be used when automatic systems may fail or when manual intervention is preferable due to specific conditions at the time. Automatic release mechanisms are designed to facilitate quick deployment without requiring substantial physical effort, which can be vital in high-stress scenarios.

Together, the combination of manual and automatic release options ensures that there are multiple fail-safes in place to enhance safety and efficiency during emergency evacuations, aligning with the principles of personal survival techniques outlined in the STCW training.
