If you're doing easy mode, you don't need to care about shiplocks. Otherwise, you need to make sure you have enough ships for each shiplock colour. Each event map will "tag" your ships in a particular colour, and on Normal difficulty and above, they don't allow ships tagged in one colour to access a map of another colour.
