Rambler said:If a ship has moved more than 12 inches in a turn (usually by using the All Power to Engines! Special Action) and is attacked by a seeking weapon in any fire arc except its fore, it may be able to evade the weapon long enough to escape any damage.
Under these conditions, the ship makes an opposed Crew Quality check with the ship attacking it with seeking weapons. If the ship manages to win the check, then the seeking weapon attack is ignored.
It states a single check, not multiple checks. Either all Seeking Weapons are Evaded or none are.
The rule uses the singular 'weapon' in three instances, implying that you roll a check against each weapon.
