Just messed about with this as practice for pointer scanning really, (thanks dopefish for the help with that) as the fov is fine as it is though I do prefer it slightly more zoomed out.
The fov is 70 vertical by default (100 degrees horizontal), I prefer 78, (110 horizontal) for this game. I don't know if the fov changes automatically for those with multiple monitors but if not then at least this tool will be useful for that :D
I recommend you preorder, the game looks like it's going to be amazing - http://www.piratesofnewhorizons.com/

Just load it up and leave it running as you play the game.
Whilst in game, press
Left arrow - Default fov (100)
Right arrow - 110
Up arrow - Increase fov by 5
Down arrow - Decrease fov by 5
