If your goal is strictly to meet a legal requirement, that's fine. However, I believe the tubular deigns must be nearly perpendicular to the signal to work at all. Even the angle of a shroud degrades their performance, let alone heeling.

Re: Should i use a radar reflector

I've got an 80's era Fruno aboard. I am learning to use it by using it in the day time with good visibility. The canal to my dock is more than a mile long. One day I was watching the radar, looking up to see what the radar was showing me and I noticed one particularly bright target. Turned out to be the one sailboat with a cheap type reflector, the other boats around it were not particularly noticeable.

New radar maybe, and probably are, capable of discerning the target better, as Main's posting clearly shows, but what percentage of boats out there have got the latest and greatest?

A nav class I was in made the point that the best radar reflector aboard a boat from the factory is the engine in the bilge, mostly shielded by the water.

The new 3G and 4G radar systems are absolutely awesome. Take a look at Broadband 3G

Why I do not bother with a radar reflector

After reading the report of the sinking of the yacht Ouzo I have never bothered with a radar reflector. There are plenty of other reports of collisions where ships' watchofficers were not looking at the radar (ie Ella Pink Lady collision with Silver Yang in 2009).

I assume that you are invisible to these ships and you need to avoid them.

NB: in my area these is no legal requirement

Re: Should i use a radar reflector

Does Heeling affect the efficiency of a radar reflector.

I would say no, the cells are 90 degrees and symmetrical and designed to reflect the signal back no matter the angle.

If heel affected efficiency, then one could also say the angle of the boat with the radar to the sailboat's heading would also affect the efficiency. And that's not the case.

Where's the input form civilian and military radar engineer experts on the effect of heeling?

I miss-spoke - I should have studied the UK tests first. Hell does reduce efficiency.

Re: Should i use a radar reflector

Would you need a radar reflector on a steel sailboat? or is the steel hull good enough?
Or maybe the hull it self is too low in the water to get picked up properly?

In the older days they used to fill up their wooden mast with aluminium foil and this was supposingly better than the radar reflecter that existed in that time, I would guess that it's still better than the modern reflectors.
