A shipboard ballista is essentially a Huge heavy crossbow that is fixed in place. Its size makes it hard for most creatures to aim it; thus, a Medium creature takes a -4 penalty on attack rolls and a Small creature takes a -6 penalty. It takes a creature smaller than Large two full-round actions to reload the ballista after firing. A shipboard ballista has a swiveling mount, and is usually placed near the bow of the ship. The cost of the ballista includes the mount.
