Based on "Peggy Days" Tab with a few alterations.
Please be aware this is my first tab so apologies for any mistakes!

You can play a regular C instead of C/G. Both are fine but I think C/G sounds nicer.

C/G                                F
Set the sails I feel the winds a'stirring
Am                                G
Toward the bright horizon set the way
Em                                  F
Cast your wreckless dreams upon our Mayflower
G                              C/G
Haven from the world and her decay

C/G                                       F
And who could heed the words of Charlie Darwin
Am                             G
Fighting for a system built to fail
Em                               F
Spooning water from their broken vessels
   G                            C/G
As far as I can see there is no land

F     C/G     Em         Am         G
Oh my god, the water's all around us
F     C/G         G     C/G
Oh my god, it's all around

[Short Instrumental - Just repeat chords for "Oh my god, the water's all around us, Oh 
god, it's all around"]

C/G                                       F
And who could heed the words of Charlie Darwin
Am                                  G
The lords of war just profit from decay
    Em                                     F
And trade their children's promise for the jingle
    G                                     C/G
The way we trade our hard earned time for pay

F     C/G        Em                Am    G
Oh my god, the water's cold and shapeless
F     C/G         G     C/G
Oh my god, it's all around
F     C/G    Em               Am   G
Oh my god, life is cold and formless
F     C/G         G     C/G
Oh my god, it's all around

[Ending of song played same as the short instrumental]

At the end of the song, Fmaj7 is quickly played before finally finishing on C/G.


Thanks to Peggy Days for the help!

Good luck and let me know what you think!
