Answer: Grant the motion, because there is no evidence that the crew operated the ship negligently.
Step-by-step explanation:
The court should rule by granting the cruise ship owner's motion due to the fact that the passenger has not been able to establish a case of negligence against the ship.
It should be noted that in order to establish a prima facie case for negligence, the plaintiff in this case must be able to show a duty of care, then a breach of that duty, a proximate cause, and the damages. However, in this case, the passenger doesn't have enough evidence to back up his claim.
