Very simple question that I assume I missed the rules on. When a huge ship hits a a small or large ship, the small ones die, and a small or large ship rolls an attack die like an asteroid if they collide, and you follow base touching rules.

But unlike an asteroid can your maneuver template go through a huge ship without effect? I assumed yes.

Yes. The rules for small ship overlapping state that you follow all the normal rules for base overlap but roll for damage like an asteroid. (Transport insert page 5)

You can move thru a Huge ship with your template and suffer no ill effects as long as you clear the huge ship and don't overlap it.
