Odd rocks round ship, and now unfortunately resulting in crash (4,4)

'crash' is the definition.
(I know that crash can be written as doss down)

'odd rocks round ship and now unfortunately' is the wordplay.
'rocks' indicates anagramming the letters.
'round' is an insertion indicator.
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'and' is a charade indicator (letters next to each other).
'unfortunately' indicates anagramming the letters (a bad or unfortunate spelling).
'odd' anagrammed gives 'dod'.
'dod' going around 'ss' is 'dossd'.
'now' anagrammed gives 'own'.
'dossd'+'own'='DOSS DOWN'

'resulting in' acts as a link.
