Examples are acetone cyanohydrin, carbon disulphide, cresols, naphthalene and tetraethyl lead. * Category B - Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify the application of special anti-pollution measures. Examples are acrylonitrile, carbon tetrachloride, ethylene dichloride and phenol. * Category C - Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a minor hazard to either marine resources or human health or cause minor harm to amenities or other legitimate uses of the sea and therefore require special operational conditions. Examples are benzene, styrene, toluene and xylene. * Category D - Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a recognizable hazard to either marine resources or human health or cause minimal harm to amenities or other legitimate uses of the sea and therefore require some attention in operational conditions. Examples are acetone, phosphoric acid and tallow. 0 Reserved for future use Wing in ground (WIG), all ships of this type Wing in ground (WIG), Hazardous catagory A Wing in ground (WIG), Hazardous catagory B Wing in ground (WIG), Hazardous catagory C Wing in ground (WIG), Hazardous catagory D Wing in ground (WIG), Reserved for future use Wing in ground (WIG), Reserved for future use Wing in ground (WIG), Reserved for future use Wing in ground (WIG), Reserved for future use Wing in ground (WIG), No additional information fishing towing towing length exceeds 200m or breadth exceeds 25m dredging or underwater ops diving ops military ops sailing pleasure craft reserved reserved High speed craft (HSC), all ships of this type High speed craft (HSC), Hazardous catagory A High speed craft (HSC), Hazardous catagory B High speed craft (HSC), Hazardous catagory C High speed craft (HSC), Hazardous catagory D High speed craft (HSC), Reserved for future use High speed craft (HSC), Reserved for future use High speed craft (HSC), Reserved for future use High speed craft (HSC), Reserved for future use High speed craft (HSC), No additional information pilot vessel search and rescue vessel tug port tender anti-polution equipment law enforcement spare - local vessel spare - local vessel medical transport ship according to RR Resolution No. 18 passenger, all ships of this type passenger, Hazardous catagory A passenger, Hazardous catagory B passenger, Hazardous catagory C passenger, Hazardous catagory D passenger, Reserved for future use passenger, Reserved for future use passenger, Reserved for future use passenger, Reserved for future use passenger, No additional information cargo, all ships of this type cargo, Hazardous catagory A cargo, Hazardous catagory B cargo, Hazardous catagory C cargo, Hazardous catagory D cargo, Reserved for future use cargo, Reserved for future use cargo, Reserved for future use cargo, Reserved for future use cargo, No additional information tanker, all ships of this type tanker, Hazardous catagory A tanker, Hazardous catagory B tanker, Hazardous catagory C tanker, Hazardous catagory D tanker, Reserved for future use tanker, Reserved for future use tanker, Reserved for future use tanker, Reserved for future use tanker, No additional information other type, all ships of this type other type, Hazardous catagory A other type, Hazardous catagory B other type, Hazardous catagory C other type, Hazardous catagory D other type, Reserved for future use other type, Reserved for future use other type, Reserved for future use other type, Reserved for future use other type, No additional information Reserved for regional use Reserved for future use 55 Distance from bow to reference position See 3.3.8.2.3.3 Figure 17 page 48 of ITU-R M.1371-1 See 3.3.3 Figure 42 of ITU-R M.1371-3 m 0 10 Distance from reference position to stern See 3.3.8.2.3.3 Figure 17 page 48 of ITU-R M.1371-1 m 0 11 Distance from port side to reference position See 3.3.8.2.3.3 Figure 17 page 48 of ITU-R M.1371-1 m 0 63 m or greater 12 Distance from reference position to starboard side See 3.3.8.2.3.3 Figure 17 page 48 of ITU-R M.1371-1 m 0 63 m or greater 13 Method used for positioning 0 undefined GPS GLONASS combined GPS/GLONASS Loran-C Chayka integrated navigation system surveyed 1 Receiver autonomous integrity monitoring flag not in use in use 0 Data terminal ready 1 1 available not available 0 Not used.
