Difference between a lifeboat and a rescue boat

Hello everyone!
Do you know the differences between a lifeboat and a rescue boat?

While many people consider them interchangeable, there is a clear difference between lifeboats and rescue boats.
A lifeboat is used to sustain the lives of those in distress after abandoning ship, whereas a rescue boat is used to retrieve individuals in distress from the water and return them to the ship.

The LSA code outlines the distinct equipment and design characteristics needed for each type.
