This video is for novices to radar or skippers who aren't using it all the time and get rusty. There's a lot more to be said, but that can take hours. Here, I just talk for five minutes about how radar can keep you basically safe. If you're having doubts about which buttons are the most important, this is a useful starting point.

I love radar! Great video as always, Tom, many thanks. Radar? An old Merchant Navy officer's saying: "What you don't know can be dangerous. What you don't know but think you know can be much worse!" Or another Merchant Navy saying: "Radar? An electronic device for assisting with collisions!" I think the Col Regs used to say, "Assumptions shall not be made on the basis of scanty information, especially scanty radar information!"

Very good... too bad most sailors don't know even the basics. When I used to teach flying, I used to tell my students that the things that were moving across your windscreen were not the issue... it was the "bug spots" that didn't move that were going to eventually grow into sledge hammers that would kill you. It doesn't matter if it was another plane or a mountain top or a patch of ground... if it isn't moving across your windscreen, you are going to hit it. It is an important skill to learn to be able to quickly discern which objects aren't moving when the rest of your field of view is moving (the trick is to look for objects that seem to be moving against the moving background as your eyes are very good at picking out movement). Same thing applies in cars, boats... or radar. Those items that aren't moving are on a collision course with you (unless of course you are both stopped). The B&G radar is well setup for this and this technique can also be used to figure out if a storm cell is going to intercept you (and what you need to do to avoid it). I'd like to see more of these Tom.

I love that you still refer to them as Brookes and Gatehouse. Brilliant. How it's integrated with the newer Zeus etc screens is fantastic and the reduced power consumption of these new 3/4G radars is excellent. Thanks for this overview.

Clear and to the pint as usual. personally, I prefer North up on all my navigation instruments. wich is corresponding with the good old and trusty paper charts on my chart table. And maybe a little late happy new year and may the wind blow all our sorrows of past year away

Welcome to lockdown, series 2. I loved my radar, never had AIS. Nearly had a couple of wooden fishing boats off Algeria one passage, no lights, no reflector, no nothing. Number one eyeball or keen ears!

@billgiles3261 3 года назад

Don’t knock AIS, you’ll find that radar supplements it nicely.

@TomCunliffeYachtsandYarns 3 года назад

Quite agree Bill. Using them together is a real joy.

@kevinnurse9936 2 года назад

Tom was absolutely correct about the RELATIVE bearing. I hesitate to correct him, but his suggestion that another vessel on a constant handheld compass is coming towards you, isn’t correct. You could immediately turn 90 degrees (away from the other vessel) and it’s compass bearing will be the same. I think he really meant to say a constant RELATIVE handheld compass bearing will lead to a collision. The observer would need to use the ships heading as the reference direction (just like the radar does) when using a handheld compass for relative bearing checks.

Hello Tom. I have just come across your channel (and have subscribed). I spent 2 years on a New Zealand Shipping Co Ltd training ship as a Deck Officer Cadet, have owned a number of boats including a 34 foot Colvic Watson Motorsailer. It was actually 11 mtrs OA because I added a bowsprit for sailing in the archipelago on the Eastern coast of Sweden. My radar was far less sophisticated than yours so I found this video fascinating. By the way, I also like Classic cars and own a 1933 Austin Ripley which was the actual car shown in the Paris and London motor shows in 1934. Regards Michael

@TomCunliffeYachtsandYarns 3 года назад

Good to hear from you Michael. The bowsprit sounds like a great idea for a bit of extra rag in the archipelago. What a lovely place to sail. Keep your tappets sweet, Tom

@stefflus08 2 года назад

I was a radar and nav man in the Royal Norwegian Navy. We always had N up, so it corresponded to the chart. We always strived for a handful of redundancies on any course, mostly optical, but another could be to set the distance ring as one of the indicators to time a turn. -Also we set a parallel course line at a wanted distance to shore. Can your radar do that?

On an ocean passage and before affordable radar, what did you do to avoid contact?

@nathandecrom2409 3 года назад

keep a sharp lookout and try to stay out of common shipping lanes/passage lanes

@Themothershipsailing 3 года назад

Thanks!! I’m looking at installing radar in conjunction with AIS. Any tips for how to use them efficiently together? My AIS has so far been useful for CPA and TPA and identifying the object - but of course it won’t pick up those without transponders or things that are not ships..

@woolyimage 3 года назад

I would just use the AIS for helping to identify targets but use the radar for everything else, if set up properly the radar will show the AIS data on the radar screen. Do take some time to familiarise yourself with your radar and if you get a chance even do a course to help you get up to speed with your radar. There are lots of youtube videos to help as well in these covid restricted times. Practicing in fine weather is a good idea as you can visually check whats actually happening. Hope this has helped.

@itsjustplainsailing5189 3 года назад

Thank you Tom; have recently added radar to my boat; mainly for collision avoidance whilst sleeping on long passages solo sailing..quick scan at 30nm etc, cross check with ais and go get ya head down. Enjoyed your no nonsense approach though. Just out of curiosity, the flue pipe over your shoulder..? Is that from your solid fuel stove? I have similar a set up but never seen a top cap like that. Is it some form or silicon flap arrangement? Be interested to know. Happy moonsl’s .

Don’t turn when there is no risk of collision, and when there is but you don’t see it, don’t turn to port :)

@whitefields5595 3 года назад

I've always struggled with folk that insist on 'North Up' whilst making way. As skipper of the Birmingham Navy I banned it years ago and only permit its use as a reference in passage planning. I would be interested in hearing from an experienced sailor if there are any benefits at all .... or indeed any risks of using 'course up'? I suppose on long open-water passages it does not matter much and helps keep the chart table tidy. However anytime offshore, particularly pilotage near the hard bits, then you need that instant spacial orientation as soon as you look up?

@kimfucku8074 3 года назад

I only use head up! When using the radar my priority is the traffic relative to my course. There are pros and cons but it depends on your priorities while under way. Modern plotters give anyway all information with a click of a button. If you want to take a true bearing you always can switch to North Up if you don't like to caclulate.

@woolyimage 3 года назад

ALL commercial ships use radar in north up mode. They do so for a reason, in that professionals are trained to plot manually ( or at least they used to be !) This is much simpler using north up. Using the standard system you can easily determine a targets speed, course and aspect as well as cap and tcpa. It is also a benefit if you are changing course often or the heading is hunting around. In north up only the heading line moves in head or course up the whole picture moves around which can disorient the observer. The short video shows how a basic manual plot is done ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k3CyaRZY1CE.html

@MrSmithToday 3 года назад

@woolyimage 3 года назад

I think that if your meaning to use radar you really have to know the basics or it could get messy ! Find out about OA WO and WA lines which are the basics of plotting. You can buy paper plotting sheets and do some practice at home its not difficult. Many modern radars have some sort of automatic plotting system which helps do this for you but you should still understand the basics. As to orientation i always use north up, which will show the features you are seeing on your chart or plotter, as you are usually using radar for more than collision avoidance. Do practice when possible in daylight in fine weather where you can visually relate to things. Finally remember to look through the colregs for specific mentions relating to the use of radar.

@TomCunliffeYachtsandYarns 3 года назад

Speaking as an 'old lag' instructor examiner, I can state the sad fact to be that most people are not going to get to grips with radar plotting. What you say is dead right, although most professionals I know use 'course' or 'head up' as default. So do I. This was a totally basic intro for beginners and I did point this out. There is so much more to be said, but many will not progress much beyond this level, especially those who cannot spend long periods at sea every year. It's important to help them to get the basics right, I think. Amway, thanks for your input which is valued. Tom
