Which of the following is part of the required equipment for a lifeboat?

The required equipment for a lifeboat includes essential items that ensure the safety and functionality of the lifeboat in emergency situations. A boathook, painter, and whistle are critical components.

The boathook is used for securing the lifeboat to a ship or dock, providing an easy means to catch lines and assist in handling the vessel. The painter is a long line that secures the lifeboat to the ship and is vital for pulling the lifeboat away from the vessel once it is launched. The whistle serves as a signaling device, which is crucial for communication in emergency scenarios to attract attention or indicate distress.

While life jackets and flares are indeed important safety equipment, they are not specifically listed as required items for the lifeboat itself. Other options include items that may be useful in various boating scenarios but do not represent the standardized essential equipment mandated for lifeboats in marine safety regulations.
