Famous raft (3,4)
I believe the answer is:
kon tiki
'famous raft' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for kon tiki that I've seen before include "Raft used by Norwegian explorer, Thor Heyerdahl" , "Thor's craft" , "Thor Heyerdahl's raft" , "transport for Thor?" , "Thor Heyerdahl craft" .)
