Which release capability will release the lifeboat with a load on the hooks, using a hydrostatic interlock to ensure waterborne before release?

• A. Normal offload release capability
• B. On-load release capability
• C. Simultaneous release
• D. Red color

Answer: (B)

On-load release capability is the system designed to release a lifeboat while it is still loaded on the ship’s falls, with a hydrostatic release unit ensuring the boat is waterborne before the release occurs. The hydrostatic interlock uses water pressure to confirm submersion, preventing premature release on deck and guaranteeing a safe separation once the boat is in the water. This matches the scenario of having a load on the hooks and needing release only after the lifeboat is waterborne. Normal offload release would require the boat to be fully lowered and off the hooks before releasing, and simultaneous release or a color indicator don’t describe this waterborne, load-on-release behavior.
