Beer knocked back by far ramp in dock (7)

I believe the answer is:

slipway

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

'dock' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'beer knocked back by far ramp' is the wordplay.
'beer' becomes 'pils' (Pilsner beer).
'knocked back' shows that the letters should be reversed in order.
'by far ramp' becomes 'way' (I can't justify this - if you can you should give a lot more credence to this answer).
'pils' backwards is 'slip'.
'slip'+'way'='SLIPWAY'

'in' is the link.

Can you help me to learn more?

(Other definitions for slipway that I've seen before include "Launch slope for ships" , "Launching place" , "where vessels are launched" , "Launch ramp" .)
