Yes, the chords Jeremiah posted are from the MacLean songbook but whoever did those chords was not directly transposing them from Dougie's playing. Dougie plays this in open C-minor tuning capoed on the sixth fret, putting the key in F# minor. I looked at my copy of Dougie's interactive cd but everything there is visual images so the cd shows images of the guitar and where Dougie's fingers fall on the fretboard. I'm not sure how to transfer that info to this post but I did find the following chord progression using standard guitar chords in the key of F#-minor for "Ready for the Storm":

F#m
|:[ / / / / ][ / / / / ][ / / / / ][ / / / / ]:|
    F#m                                                F#m/E
The waves crash in, the tide rolls out, it's an angry sea but there is no doubt
         Dmaj7                                    E2
That the lighthouse will keep shining out to warn a lonely sailor
        F#m
And the lightning strikes and the wind cuts cold
           F#m/E
Through the sailor's bones, through the sailor's soul
         Dmaj7                                      E2
Till there's nothing left that he can hold except a rolling ocean

F#m   Dmaj7               C#m7
Oh I am ready for the storm, yes sir ready
F#m   Dmaj7           C#m7                            F#m
I am ready for the storm, I'm ready for the storm

Oh give me mercy for my dreams 'cause every confrontation seems to tell me
What it really means to be this lonely sailor
And when the sky begins to clear, the sun, it melts away my fear
And I cry a silent weary tear for those who mean to love me

F#m   Dmaj7               C#m7
Oh I am ready for the storm, yes sir ready
F#m   Dmaj7           C#m7                            D2/F#
I am ready for the storm, I'm ready for the storm
E2            D2               E2         D2/F#              E2         D2            E2

The distance it is no real friend and time will take its time
And You will find that in the end it brings You me, this lonely sailor
And when You take me by the hand and You love me, Lord, You love me
And I should have realized I had no reasons to be frightened

F#m        Dmaj7              C#m7
Oh I am ready for the storm, yes sir ready
F#m Dmaj7           C#m7
I am ready for the storm, yes sir ready
F#m Dmaj7           C#m7
I am ready for the storm, yes sir ready
F#m Dmaj7           C#m7                            F#m    F#
I am ready for the storm, I'm ready for the storm
