I agree with Joey, capital ship battle need to be scripted using waypoints, unless you just want ships circling around each other ten minutes at a time. You can also set up the waypoints so that you present the most available firepower.
Example: the Sobek has 2 main beams, both facing forward with rather generous firing arcs, but once within a certain distance of its target, it simple circles around that ship, presenting it with a broadside attack. Despite the Sobek's firing arcs on its 2 main beams, only one can attack its target in a broadside engagement. A more effective way to implement the battle would be to put the Sobek on a path that would keep it in the aft quarter of its target, thus always presenting that target with both beams.
