Okay so two things that are very interesting to me here:
1. The Sea Dog does a ranged attack, but it can also capture enemy ships? The latter ability was not explicitly shown, so I've no idea if it has to be at melee range to do so, but a ranged Privateer still sounds pretty dang awesome.
2. So is there no more zone of control? While it's true that the Red Coats spend only 1 move to disembark, it was doing so within what used to be the ZoC of the enemy unit, and I'm pretty sure that still would trigger ZoC in Civ5.
I like that the English still get to keep their naval movement bonus with the Royal Navy Dockyard. +1 move isn't as sweet as +2, but at least the RND gives a bunch of other bonuses.
