For all those that asked, i'm on VH/H difficulty, and there's another thing, i see no differnce of the campaign AI from normal to VH, i think that setting may be broken.

I've tried VH battles but the AI is still unbelievably stupid, but i'm convinced they get stat bonuses on VH, because i've had 1 pirate ship with 2 hull strength take out 4 of my own ships which had 4, 3 and 2 hull strength, 2 of which had more guns than the pirate ship did and one of which had more firepower than the pirate ship.
