1. Conventional Lifeboats
Conventional lifeboats are the most traditional type of lifeboats used on ships. They are typically enclosed, which helps protect passengers from harsh sea conditions and fumes.

- Made from steel or fiberglass.
- Equipped with survival supplies like water and first aid kits.
- Can be launched by davits (crane-like devices).
Uses:
- Commonly found on cargo ships and older passenger vessels.
- Used for abandonment in case of sinking or severe fire.
2. Freefall Lifeboats
Freefall lifeboats provide a rapid means of evacuation, as they are designed to be launched from a ship by sliding down a ramp and entering the water without human intervention.
Features:
- Aerodynamic shape for a smooth launch.
- Strong construction to withstand the impact of hitting the water.
- Typically fully enclosed.
Uses:
- Ideal for oil rigs and tankers where quick evacuation is necessary.

- Often include a canopy for protection against the elements.
Uses:
- Common on modern cruise ships, yachts, and fishing vessels.
- Used when space is limited and quick deployment is required.
4. Rigid Inflatable Boats (RIBs)
Rigid Inflatable Boats combine the features of rigid construction with the buoyancy of inflatable "sponsons" (side tubes).
Features:
- Lightweight and high-performance.
- Durable hull with inflatable collars.
- Fast and highly maneuverable.
Uses:
- Often used by coast guards and rescue teams for quick response.
- Suitable for operations close to shore or in harbors.
5. Davit-Launched Lifeboats
Davit-launched lifeboats are designed to be deployed using a davit system that lowers the boat safely into the water.
Features:
- Can be either open or enclosed.
- Equipped with motor and oars.
- Provides a stable means of descent.
Uses:
- Commonly used on larger vessels with sufficient deck space.
- Allows for controlled and safe evacuation.
