You usually hear this done unaccompanied but here's my guess at the chords, pick any key, and use ( I, IV, and V... in this case G, D & C)... chords in front of the words they fall on.....
(G)Don't mind the wind nor the rolling sea
The weary night never worries (D)me
But the hardest (G)time in a sailor's (C)day
Is to watch the (G)sun as it (C)fades a(G)way
(G)It's one more day on the (D)grey funnel (G)line
