Article 8
Certificates 1. All new and existing ro-ro passenger ships flying the flag of a Member State shall carry a certificate confirming compliance with the specific stability requirements established in Article 6 and Annex I. This certificate, which shall be issued by the administration of the flag State and may be combined with other related certificates, will indicate the significant wave height up to which the ship can satisfy the specific stability requirements. The certificate shall remain valid as long as the ship operates in an area with the same or a lower value of significant wave height. 2. Each Member State acting in its capacity as host State shall recognise certificates issued by another Member State in pursuance of this Directive. 3. Each Member State acting in its capacity as host State shall accept certificates issued by a third country certifying that a ship complies with the specific stability requirements established.
