In reference to 3.1.3 of the amended MGN: ‘The notice will not be amended as it can’t be confirmed 100% that there are no products of this type currently on the market, but it is highly likely during our research that this is the case. It should be noted that Echomax has emailed Yachting Monthly to say it has contacted the MCA to express concern over their mention of ISO 8729-1:2010, as currently, there are no known passive radar reflectors which meet ISO 8729-1:2010 which has a volume limit of 0.5m3 and weight limit of 5kg. If the radar reflector meeting these standards are unsuitable for boats under 15m LOA, then owners are recommended to fit a radar reflector to the older standard EN ISO 8729:1998, which has been retained for type approval under the Marine Equipment Regulations (MSN 1874) for radar reflectors for lifeboats and rescue boats. Any radar reflector meeting the above requirements should comply with ISO 8729-1:2010. There should not be a distance of less than 20° between nulls.įor power driven vessels and sailing vessels designed to operate with little heel, such as a catamaran or trimaran, this performance should be maintained through angles of (athwartships) heel 10° either side of vertical.įor other vessels, the radar reflector should maintain this performance over 20° either side of vertical. The RCS should be maintained over a total angle of at least 280° of azimuth and not below this level over any angles greater than 10° (a null). Always keep a proper lookout, advises the MCA. Just because you have a radar reflector, doesn’t mean you will be seen.
