Jono,

Is the above scenario not just as likely with a traditional radar reflector? - if not more likely as if there is genuinely "wreckage" there is a fairly good chance the electrics won't last long and so the see me will suddenly "die".

Yes, sorry didn't mean to mislead anyone.

Anyone considering reflector options may be interested in the study carried out by QinetiQ as hosted here on yachting and Boating world: http://www.ybw.com/pbo/pdfs/radar_reflectors.pdf

The study was commissioned by the MAIB after the sinking of the Ouzo. It examines the performance of a number of reflectors on the market, including the Sea-Me. What is very striking is the degradation of performance of most reflectors at even quite small angles of heel. Also note how the Plastimo tube reflectors perform - even the bigger one is pretty much useless even when virtually perfectly upright - and I have seen these fitted to numerous RIBs.

The Sea-Me performed pretty well and I think it's a good option compared to a passive reflector, assuming you have the power required. it also looks a whole lot better than an octahedral bit of tin bolted to your A-frame! It won't work on S-Band radars though.

Decision made

Some usefull infor from you all.
JW + Jono thanks
JC thanks for the post to the report. very interesting.

I will have a Sea-Me and a fixed TriSphere reflector.

The (commercial Boats) who might be on S band will be very visible to me (on radar) due to their size. Also with AIS I should pick them up earlier than on radar alone. No disrespect to leisure boaters but I see them as being more risk to me than commercial shipping - collision wise.

Decision made - now move on to the next thing to understand.. lifejackets..
