Alright, this is "Never Seen the Sea" by Gavin Clark. I looked all online for the tab, 
find any, so I decided to write it myself.

At first I tried playing it with one guitar and decided it was pretty much impossible. 
I added two guitar parts

GUITAR 1:
----------------------------------------------------------------------|
-11--11-11--11-11--11--11-11--11-11---6---6-6---6-6---4---4-4---4-4---|
---11-----11-----11--11-----11-----11---6-----6-----6---4-----4-----4-|
----------------------------------------------------------------------|
----------------------------------------------------------------------|
----------------------------------------------------------------------|

GUITAR 2:
--------------------------------------------|
---------------4----------------------------|
-------------------3-----3------------------|
-----4-----1-----------------3-------4---1--|
--------4-------------1----------2----------|
-2------------------------------------------|

The two guitar parts should fit together perfectly with a little practice in tempo. Have 
:)
