Briefly take old vessel back round a volcanic island (8)

I believe the answer is:

krakatoa

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

'volcanic island' is the definition.
(I've seen this before)

'briefly take old vessel back round a' is the wordplay.
I cannot quite see how this works, but
'briefly' could be 'k' and 'k' is found within the answer.
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is present in the answer.
'old' could be 'o' (abbreviation) and 'o' is found in the answer.
'a' is present in the answer.
The remaining letters 'kata' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
