I believe the answer is:

speedboats

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

'fast transport to be passed with difficulty' is the definition.
I can't judge whether this defines the answer.

'to be passed with difficulty' is the wordplay.
'with difficulty' is an anagram indicator.
'to'+'be'+'passed'='tobepassed'
'tobepassed' anagrammed gives 'SPEEDBOATS'.

Can you help me to learn more?
