Life Rafts

Life rafts are emergency devices designed to ensure survival in the event of a shipwreck or other dangerous situations at sea. They are built to be robust, easy to maneuver, and able to withstand harsh conditions.

Life rafts are generally constructed of durable, buoyant materials, such as reinforced plastic or rubber. Their structure is designed to maintain stability in the water, even in rough seas or high waves. The base is usually equipped with an inflatable platform, which can be adjusted to the number of people on board, and buoyancy tubes.

Characteristics

1. Load capacity 
2. Shelters and protection 
3. Anchoring System : It is common for rafts to be equipped with ropes or anchoring systems to be tied to the vessel or used as a lifeline during evacuation.
4. Survival gear : May contain flares, food and water rations, lighting devices, bandages and other first aid medical equipment, as well as oars or motors for navigation.

Operation

Life rafts are usually deployed aboard the vessel in easily accessible locations. In an emergency, they are inflated automatically or manually, and their structure quickly deploys to provide a floating surface. Crew and passengers are then routed aboard the raft, which can be towed or navigated autonomously to safety.

Types of Life Rafts

1. Inflatable life rafts : The most common for modern vessels, which inflate automatically or manually.
2. Rigid rafts : Rarer, but used in particular circumstances, they are made of rigid materials and do not require inflation.

Usage

Life rafts are primarily used on ships, ferries, and other vessels as part of mandatory safety equipment. Their effectiveness depends on their timely deployment in an emergency, proper equipment, and the ability to navigate or be rescued in open water.

In short, life rafts are vital devices that can mean the difference between life and death in a maritime emergency, designed to protect and ensure survival in critical situations.
