Floats a good deal (5)

I believe the answer is:

rafts

I believe this clue is a double definition.

'floats' is the first definition.
(raft is a kind of float)

'a good deal' is the second definition.
(thesaurus)

(Other definitions for rafts that I've seen before include "Flat boats" , "Flat floating structures" , "Flat floats" , "Flat, floating platforms" .)

I've seen this clue in The Telegraph.
