When firing boresight weapon using miniatures does it need to center point or just cross the base.
It needs to be dead on, all measuring for capital ships is done from the flying step or the central red dot on conters.
It is a good idea I found to inform the opponent in the moving phase of any Boresight targets (just make sure that you target those ships that have already moved). This way if things get knocked during play it avoids debates.
