I've just checked the chords to Make and Break Harbour" in Stan Rogers' songbook and it seems as if I've missed some (copy and paste into WORD/TIME/12 to line up chords):

G------------------------------Em------------------C-----------------------D
They've tipped and they've shoveled, they've trimmed and they've stored,
------------C----------------------------D
And she's down to her load-line as ever;
------G-----------------G7--------------C------------Bm
The bridge is swung round as she's leaving this town,
-------------D----------------------D7
And she's off to the dark o' the river.
------G-----------Em--------------C-----------D
Fare-well to the grime and the dust of the tips,
---C---------------------D--D7
It may be a month or for-ever:
-------G-----------------G7------------C---------------Bm
She's watched by the ships and the ghosts on the slips
---------D-----------------------D7---------G
As she ploughs through the dark o' the river.


-------C-----------D----------------G----------Em
Fare-well to the grime and the dust of the tips,
---G---------Em--------C
It may be a month or forever:
-------G-----------------Em------------G--------------C
She's watched by the ships and the ghosts on the slips
---------D-----------------------D7---------G
As she ploughs through the dark o' the river.

I'm still not sure of the Bm's but what the heck!

Cheerily,
Charley Noble
