I'm sorry, but after post, the position of the chords over the words doesn't remain as it ought to be. This could be clear:

The Dia(Cm)mond is a ship(Bb), my lads, for(Cm) the Davis Strait she's bound(Bb)
And the quay(Cm) it is all gar(Bb)nished(Cm) with bon(G7)nie lassies round(Cm)
Captain Thomp(Cm)son gives the or(Bb)der to(Cm) sail the ocean wide(Bb)
Where the sun(Cm) it never sets(Bb), my lads(Cm), nor dark(G7)ness dims the sky(Cm)
So it's cheer(Cm) up(Bb), my lads(Cm), let your hearts never fail
While the bonnie ship(Bb) The Dia(Cm)mond goes(Bb) a-fish(Cm)ing for(Bb) the whale(Cm)
