Neither the CRB nor HG 'alternative movement' p83 seem to indicate the order in which ships move. Although one might assume it is based on initiatve that doesn't seem to be clearly expressed. Of course, it doesn't seem to make much difference if you're not using HG 'alternative movement', but if you are there would seem to be a tactical advantage in moving last.
Therefore, should the lowest initiative ship make their vector movement first? Seems to make sense, but can anybody cite a rule or offer any other thoughts on the matter?
