AIS transmits from anywhere, or at least it can appear to, which is all that matters. There are many virtual AIS buoys and rocks will follow.AIS only picks up vessels transmitting and many aren't, neither are rocks and buoys.

My radar is on a pole at the stern. Whether that offends your eye I don‘t know, but it is practical, reducing weight aloft and as a bonus reducing sea-clutter.To me, two major downsides are the visual and the performace. The dome looks like a birds nest and disturbes the air flow around the sails. AIS us used by almost all steel ships - the ones that are hard to hit.
I'm seriously considering fitting radar in my planned upgrade of electronics., so all this discussion is very helpful! I see it as being potentially useful a) in poor visibility, b) to give more information about local weather conditions, c) to help with navigation where shores are low and difficult to distinguish by eye and d) to spot other vessels or objects in the water, especially those that don't transmit AIS. I don't NEED it, but I can see that it is a useful AID. I would have it integrated with AIS and charts on a plotter, to maximize it's synergism with other equally valuable systems.My radar is on a pole at the stern.

I have used mine a handful of times in anger during the last twenty years but each time it was indispensable. On a couple of occasions I was able to be of assistance to other yachts nearby who had set out without radar. I don’t enjoy anxiety, and radar can convert a stressful experience into something that is almost a pleasure. There are plenty of calm days when one finds oneself motoring on autopilot with nothing to do, which are ideal times for practicing with radar, or playing as my wife calls it.
Yeah, radar is heaps ahead of AIS. Regular practice and it's a very useful tool. But it does depend on your style of sailing as you,point out.
Familiar waters, daylight hours? Not really necessary. Coastal cruising? Getting in the zone. Especially for those gazillions of boats without AIS. Well offshore or tropical sailing? Dogs doodahs for rainsquall dodging.
You could have a look at my installation on H4 if you like. I would be happy to give you a demo any time. Mine is based on the e7 and not as new as some but it should give you an idea.I'm seriously considering fitting radar in my planned upgrade of electronics., so all this discussion is very helpful!

Thanks - I'll take you up on that sometime. I'm at F25, so not far away! Not sure when I'll be there next, but I'll pm you. I'm looking at the Garmin 1223xsw bundle.You could have a look at my installation on H4 if you like. I would be happy to give you a demo any time.

You have already been spotted!Thanks - I'll take you up on that sometime. I'm at F25, so not far away! Not sure when I'll be there next, but I'll pm you. I'm looking at the Garmin 1223xsw bundle.
See my quotation of the relevant Regulation in my Post#35.Another issue is that if fitted, Colregs requires its use in reduced visibility. I know a few clubs that don't fit Radar because they're not sure they'll have anyone on board who can use it.
How do you know Cheeky Girl is a ‘she’?Two of my key requirements are food and water. Do you need me to specify them .... or would you be able to infer them from the fact that I am clearly a human being?
Now, the OP is the owner of a sailing vessel and she is asking about radar and how often people actually use it so it only takes a similar stretch in imagination to infer what she believes her requirements might be.
However, in the context of my phrase "None of that means that AIS won't satisfy the OP's requirements", it is clearly explicit that AIS might, or might not, satisfy the OP's requirements without me needing to specify what those requirements might, or might not, be as I am obviously leaving that assessment up to the OP.

My radar gets occasional use - fog and approaching rain squalls mainly. It's not the big ships that you need it for, as they have ais, but the little mobos that go out fishing in fog!
As others have pointed out. There’s a bit in IRPCS about keeping a lookout by all available means.Was on watch but as helmsman on a dredger whilst the mate spent his time with his head in the radar,Ihadto call him out as a small craft was close by,he hadn’t picked it up amongst the clutter
Exactly so. Good point well made.Then either you've never sailed the west coast of Scotland or you're never out after dark. Scotland is the perfect place for radar, with steep mountains either side of narrow yet extremely deep lochs. On a dark and cloudy night with no fog and no other boats, radar might be the best way to make your way up a loch that has no street lights or houses on the shores. I've been there, and GPS doesn't quite cut it in terms of confidence at 6kt under sail in pitch black!
It should be noted that if you have a radar you are obliged to use it at night and in bad visibility:
Rule 5 states: Every vessel shall at all times maintain a proper lookout by sight and hearing as well as by ALL AVAILABLE MEANS appropriate to the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.
I think the idea might be that you look up and out as well as down at the screen?I wouldn't interpret that as meaning that you had to use it, just that you had to consider it's use if it was available. I can't imagine that "I was looking at Radar" would cut it as an excuse if you mowed down a couple Optimists in perfect visibility. If you were in fog and didn't use it that might be a different story.

True, but that means either you need two people on watch or do what we do and have the radar screen visible from the companionway.Difficult for those who mount the display below decks where it can't be seen or operated from the cockpit![]()
