Radar reflectors, do they really work?

Do they or don't they.
Do you have one on your rib ??

The small diameter tube types certainly aren't worth it.
A passive unit like the Echomax or Tri-Lens models is better than not having one at all, as the Qinetiq tests have shown. At least with a motor boat you can ignore the heeling factor applied to sail.
Obviously with a reasonably well-powered boat, you have more ability to manoeuvre out of a potential incident that under sail.
Since the Ouzo report, Echomax have also introduced an active unit which retails at less than the Sea-Me. It is better specified and uses less power. There's also a waterproof control box available for open boat use.
Whether it's worthwhile for the sort of boating you do is a personal decision based on type of boat, where you go, likely traffic etc. As often said, there is no substitute for an effective watch.
(and yes, I have a vested interest in supplying these units)

I fish probably no more than 3 or 4 miles off shore.
See a few big ships a bit further out maybe 3 miles or so.
I have one of those tiny plastic tubes not yet fitted .
so I don't realy know if I need one or not.
Short fishing trips lasting 5 to 6 hours.

some of the plastic tube types are not as good as they look even though they may say they are approved ect ,,,,in reality most dont seem to live up to their expectations ,,if you are operating in TEES/Hartlepool bays you need some sort of reflecter even a old octaheadral type, and with the amount of commercial shipping ,think last year was 3rd busiest port in uk . plus the Newcastle to Holland ferrrys ect further out .. its also a good area for getting sudden fog/seafretts that can come down suddenly .

The main thing to remember is that no matter how high tech your reflector / active widjet is, it's only as good as the person on watch on the bridge of the ship bearing down on you....

Under the colregs, you should have a reflector fitted if practicably possible. I can't think of many ribs that wouldn't be able to fit one some way or another. Interestingly though, the Qinetiq test showed that none of the passive reflectors on the market at the time actually complied with all the minimum standards. I chose the tri-lens which is compact waterproof and got a generally good rating.

Well as you say required in this area.
I suppose something is better than nothing.
It's going on the rib.

one of the sailing lads in the club went across to Denmark few years back .lost his reflector over the side half way back ,, so he came back with a plaggy blag and a few squished beer cans worked quite well acording to the pilot cutter .

I have an Echomax reflector on my boat and no one had collided with me yet. If you have radar you will know that even a large yacht without a reflector will show a weaker echo when end on than a smaller boat that does have a reflector. They're relatively cheap so why not fit one?

Taking that to it's logical conclusion - I've never had one at all, and nobody's ever run into me........
On a more serious note, those of you "with", how do you fit them to avoid masking the all round white & VHF aerial for a good chunk of their 360 degrees radiance? Under the crossbar makes sense, but then it's almost level with the engine, and will be partially masked by you & your crew.......

As below, top of vhf antenna does seem close to top of reflector. Will keep an eye/ear on this? Both as fitted by manufacturer.
