What is required regarding the stowage of lifeboats on cargo vessels?

Each lifeboat on a cargo vessel is required to have a launching appliance. This requirement is crucial for ensuring the safe and efficient deployment of the lifeboat in an emergency situation. The launching appliance facilitates the quick and effective launching of the lifeboat when needed, which is essential for the safety of the crew and any passengers on board.

Having a dedicated launching appliance for each lifeboat enhances operational readiness and allows for clear procedures during crisis scenarios. It's important that the lifeboats can be launched swiftly and without obstructions, so having the proper launching appliances is a key safety measure mandated by maritime regulations.

The other options do not represent universal regulatory requirements. For instance, while having a first aid kit is important for safety, it may not be a specific requirement for each lifeboat in the same way that a launching appliance is. Similarly, the stipulation about the color of the lifeboats or the absence of specific requirements does not align with the established safety protocols intended to minimize risk during emergencies.
