Radar reflectors on small vessels

Following a QinetiQ study commissioned by MAIB as a result of the loss of the yacht Ouzo the MCA has issued a Marine Guidance Note
MGN 349 (M+F) on the Carriage and Use of Radar Reflectors on Small Vessels.

The MCA strongly recommends that:

4.1 The requirements of SOLAS Chapter V Regulation 19 are complied with;

4.2 Yachtsmen permanently install, not just carry on-board, a radar reflector or RTE that offers the largest Radar Cross Section (RCS) practicable for their vessel;

4.3 Small craft owners and operators are strongly recommended to fit the best performing radar reflector possible. It is also essential for skippers to be aware that, notwithstanding the type of radar reflector fitted, in certain circumstances their craft may still not be readily visible on ships’ radars. They should navigate with caution.

4.4 The following reports published by the Marine Accident Investigation Branch are considered during the process of selecting a radar reflector:

The QinetiQ report can be accessed from the RYA website, and contains comparative data on eight radar reflectors and one radar target enhancer.
