Ah, well in that case he's gonna get the wrong impression from me, as I ticked the highest RYA thingy I have but I don't think that accurately reflects my level of experience

What's wrong with a bucket of coal? "If it splashes you're OK, but if it rattles ..."
(This post brought to you by the Dept of Obscure Film References)
I did not have too much difficulty in answering the questions and and had some quite considered comments, but as I progressed through it, my screen began to randomly jump, I was receiving requests to close down Windows, and it finally crashed. When I restored the page all my answers were blank so I just gave up.

Well done! Give the man a coconut, or possibly a lump of coal.

>Why not radar and AIS?
I thought I'd explained that, in summary radar gives much the same information as AIS but has many more benefits. For more please read my post again. If you have radar there is no point in spending more money on AIS.
It's similar with chart plotters if you are day sailing it's OK but long distance sailing you need to carry the charts in case it breaks so it's a waste of money. As I said if you do day sailing in good weather and not at night then you don't need radar or AIS, the Mark 1 eyeball suffices. Most things with sailing depend on what type of sailing you do.

I disagree.
We have both radar and AIS. The radar is only used when visibility is poor.
The AIS information is displayed on a chartplotter at the cockpit helm position. It's both interesting and helpful to see details of vessels under way or otherwise, although the information has to be taken with a pinch of salt - it's not always accurate.
For us radar is only used occasionally. However its collision avoidance role arguably makes it significantly more important.

That's a good reason to have radar, but that's not the question I asked. I know radar is a good thing to have, but you specifically said "not AIS". "Radar is better" is only a sensible justification for that statement if there were some rule that you could only have one or the other, and that's clearly absurd.
(The cost argument doesn't really stack up, in that if you're already paying two or three grand for a radar installation, an extra hundred and fifty quid for AIS practically falls into the "installation sundries" column.)

His answer is a reasonable response giving his perception, its not a right or wrong.
My answer might be different, your is different.
The kids survey was about yachtsmen’s perception rather than a precise description of what is best.
My answer depends on how I interpreted the question. Kelly’s eye probably interpreted the question in a different way from me so his perceived answer is quite different.
I took a broad definition in choosing both. As opposed to just RADAR. As “best”
If looking only for information about a Rang, Bearing, CPA and TCPA just RADAR is a real observation so clearly better.
I took the view the additional information such as name and type of vessel provided by AIS might be helpful in some circumstances so choose both as “best”
Other might feel this to be irrelevant for collision avoidance.

I don't see how either is "best". It's like comparing dancing shoes and welly boots. Both are good for their different purposes.

For the average leisure boater in most of the UK coastal waters, I don't think AIS is much use. It will only identify vessels which transmit and they are a minority of those around.

I think AIS may be easier for most amateurs to use for effective collision avoidance. The simplicity of knowing those ships, over there, are going thataway is very clear.
Most of us do not seriously use radar more than a few hours a year, we do not really have our skills up to speed when push comes to shove.
Some years ago, there was a good article in either YW or some other mag, it analysed yacht/ship collisions in the channel.
The salient points of it seemed to be;
1) Collisions are very very rare, despite us all being a bunch of WAFI's
2) Yachts with radar are no less likely to get hit. For every near miss avoided by radar, there seems to be a 'radar assisted collision'.
I assume that this is the 'Volvo syndrome', I've got radar, I don't need to worry about fog?
