New versions of those coloured moored platforms? (8)

I believe the answer is:

redrafts

I'm a little stuck... Click here to teach me more about this clue!

'new versions of those' is the definition.
I can't judge whether this definition defines the answer.

'coloured moored platforms?' is the wordplay.
'coloured' becomes 'red' ('red' can be similar in meaning to 'coloured').
'moored platforms?' becomes 'rafts' (I am not sure about this - if you are sure you should believe this answer much more).
'red'+'rafts'='REDRAFTS'

Can you help me to learn more?

(Another definition for redrafts that I've seen is " Modifies".)

I've seen this clue in the Evening Standard.
