Question 1279 Deck Safety

The correct answer is C) governor brake. The maximum speed of lowering for a lifeboat on gravity davits is controlled by the governor brake. The governor brake is a mechanical device that limits the descent speed of the lifeboat to a safe, controlled rate, as required by Coast Guard regulations. This ensures the lifeboat is lowered at a safe velocity, preventing damage to the boat or injury to the occupants. The other options are incorrect because: A) the counterweight position on the brake handle does not directly control the descent speed, B) the emergency disconnect switch is for detaching the lifeboat in an emergency, not controlling the lowering speed, and D) limit switches are used to stop the lowering process, not control the speed.
