49 CFR 39.91 - Must PVOs permit passengers with a disability to travel with service animals?
(a) As a PVO, you must permit service animals to accompany passengers with a disability.
(b) You must permit the service animal to accompany the passenger in all locations that passengers can use on a vessel, including in lifeboats.
(c) You must permit the passenger accompanied by the service animal to bring aboard a reasonable quantity of food for the animal aboard the vessel at no additional charge. If your vessel provides overnight accommodations, you must also provide reasonable refrigeration space for the service animal food.
(d) You must accept the following as evidence that an animal is a service animal: Identification cards, other written documentation, presence of harnesses, tags, and/or the credible verbal assurances of a passenger with a disability using the animal.
(e) If the legal requirements of a foreign government (e.g., quarantine regulations) do not permit a service animal to disembark at a foreign port, as a PVO you may require the animal to remain on board while its user leaves the vessel. You must work with the animal's user to ensure that the animal is properly cared for during the user's absence.
