The Merchant Shipping (Ro-Ro Passenger Ships) (Stability) Regulations 2004 (SI 2004/2884) implement Directive 2003/25/EC in the UK.
They extend application of the Stockholm Agreement’s requirements to all UK ro-ro passenger ships (including high-speed craft) operating regular scheduled international or domestic services in European waters where there is a significant wave height of 1. 5 m or more. MSN 1790 explains the regulations and contains the text of the Directive.
