This is such a beautiful song and I think it deserves an accurate tab. To get an 
idea of what the strumming pattern sounds like, listen to the recording itself.

Intro: 

  G                    Cadd9            Em7                Cadd9
I'm holding on to the hope that one day this could be made right
  G                  Cadd9              Em7                            Cadd9 
I've been shipwrecked, and left for dead, and I have seen the darkest sights
  G              Cadd9           Em7               Cadd9   
Everyone I've loved seems like a stranger in the night
  G             Cadd9                       Em7                        Cadd9
But oh my heart still burns, tells me to return, and search the fading light

  G               Cadd9   Em7         Cadd9
I'm sailing home to you I won't be long
  G             Cadd9  Em7           Cadd9
By the light of moon I will press on
 Em7      Cadd9       G
Until, I find, my love

Instrumental: G Cadd9 Em7 Cadd9

  G                   Cadd9            Em7         Cadd9
Trouble has beset my ways, and wicked winds have blown
  G                Cadd9                      Em7                           
Sirens call my name, they say they'll ease my pain, then break me on the 
  Em7
stones
  G                   Cadd9           Em7            Cadd9
But true love is the burden that will carry me back home
  G              Cadd9            Em7                 Cadd9
Carry me with the, memories of the, beauty I have known

  G             Cadd9   Em7          Cadd9 
I'm sailing home to you I won't be long
  G            Cadd9   Em7        Cadd9
By the light of moon I will press on

  Em7            Cadd9               Em7               Cadd9
So tie me to the mast of this old ship and point me home
                  Em7           G       (Em7)     Cadd9
Before I lose the one I love, before my chance is gone
           Em7      Cadd9    G
I want to hold, her in, my arms
