Stand on medium boat to get a reference point (9)

I believe the answer is:

benchmark

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

'a reference point' is the definition.
(benchmark is a kind of reference point)

'stand on medium boat' is the wordplay.
'stand on' becomes 'bench' (I can't explain this - if you can you should believe this answer much more).
'medium' becomes 'm' (as in UK clothing sizes).
'boat' becomes 'ark' (ark is a kind of boat).
'bench'+'m'+'ark'='BENCHMARK'

'to get' acts as a link.

Can you help me to learn more?

(Another definition for benchmark that I've seen is " Reference point or standard".)

I've seen this clue in The Hindu.
