According to the regulations for lifeboat falls, which action must be taken at 30-month intervals?

Correct Answer: Option B — End-for-ended

Lifeboat falls must be end-for-ended at intervals not exceeding 30 months and renewed at intervals not exceeding five years. This maintenance schedule, mandated by SOLAS and 46 CFR, prevents localized wear and corrosion, ensuring the structural integrity of the launching system remains reliable for emergency deployment.
