How a tender differs from a repair ship

What is the difference between a naval tender and a repair ship?

A tender is a one-stop support base for a flotilla; a repair ship has the narrower task of patching up vessels and equipment.

A tender supports an entire flotilla rather than serving as a floating workshop alone. It carries accommodation and facilities for the crews and vessels that rely on it. A repair ship has the narrower job of patching up damaged or worn equipment. The distinction is scope: a tender is a one-stop logistical base, while a repair ship concentrates on technical work.
