3.1 Notwithstanding the points raised in paragraph
                           1.2 above, the Standards should be applied to ships of all rudder
                           and propulsion types, of 100 m in length and over, and chemical tankers
                           and gas carriers regardless of the length.  
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3.2  In the event that the ships referred to in
                           paragraph 3.1 above undergo repairs, alterations or modifications,
                           which, in the opinion of the Administration, may influence their manoeuvrability
                           characteristics, the continued compliance with the Standards should
                           be verified.  
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3.3  Whenever other ships, originally not subject
                           to the Standards, undergo repairs, alterations or modifications, which,
                           in the opinion of the Administration, are of such an extent that the
                           ship may be considered to be a new ship, then that ship should comply
                           with these Standards. Otherwise, if the repairs, alterations and modifications,
                           in the opinion of the Administration, may influence the manoeuvrability
                           characteristics, it should be demonstrated that these characteristics
                           do not lead to any deterioration of the manoeuvrability of the ship.
                           
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3.4  The Standards should not be applied to high-speed
                           craft as defined in the relevant Code.
