Hello Ladies and thank you for another great video! I really enjoy watching your antics! If may, as an old sea dog who was trained in navigation some 50+ years ago, make a comment? I believe that a DR position is simply a function of course steered and speed through the water. Once you apply other vectors, e.g. an estimate for leeway and set caused by any tidal stream, this updates the DR position to something more accurate and is referred to as Estimated Position (EP). When you are able to fix your position using bearings, distance off, etc, this becomes your fix - the known position at that time. As an aside, do you have a sextant? Very useful for measuring the distance off a lighthouse, chimney, etc using the Vertcal Angle tables in Norie’s or Burton’s...Also worth practising fixing your position by horizontal angles, using either the sextant or compass. Very best wishes, Simon
Thank you for such a detailed reply and the great tips! We were aware of the effects of leeway but as the legs on the triangle were only a couple of nm we neglected the leeway although it may have contributed to our errors as the tide was running out at the time. We lack a sextant but our marine binoculars have a reticule that measures heights and I think that Reeds has the vertical angle tables in it. I know we have the lighthouse distance tables for when a lighthouse pops over the horizon (I forget the exact terminology). We have time to practice and improve so that is what we are going to do.
Well done. ps, it’s not dead reckoning, as I understand, that is when you estimate you position from course , distance etc. What you were doing is getting a fix.
That was some good exercise. I still have the utmost respect for the sailors back in the early days, no accurate charts, lousy compasses and no way to accurately tell the time and they still explored the world.
Sadly a lot of them never made it back, but when you consider that many ships had better conditions than some towns it must have been really rough back in the day.... In any case, we enjoyed it and we might do it more often just for the heck of it!
@@SailingYachtSaltyLass Yeah absolutely those times must of been horrible. A while back I had a gig in the maritime museum in Amsterdam. There is a replica of a merchant ship there from 1700 something. Just seeing how those brave man had to sleep and live was just mind boggling. To then conclude that life on land was even worse. We should be very happy with all the convenience we have.
I'm loving modern times. Gaynor says that if she was a time traveller, she would not go any further back than the invention of the automatic washing machine. I pointed out to her that that was roughly when she _was_ born, to which she replied "Exactly!" It was even worse for women back then. Ten percent used to die in childbirth which is why the Stepmother figure was so common. Men often had to marry a few times...
great vidio everyone should pratice the same , first time i went out on a yacht the skipper taught us to do this, i said nah ive got a gps i turned it on and the batteries were dead , lesson learned
What a great "Oops!" 😄😄 Even with an installer chartplotter backed up by house batteries, we have had the electrics go down and take everything out. On that particular day we just navigated by compass but it was really easy because we were well offshore.
I'm impressed, well done to both of u, remember it was ur first try, I'd rather be on Salty Lass and get lost than on some other crazy Looneys boat. I found that really interesting, Thank you both for having a go, because I can guarantee there's a lot of so called sailors out there who wouldn't even know where to begin. Salty Lasses are Legend!!!!💯💜👍
Thanks 👍👍 It was a hoot to do and we were never going to get lost in Belfast lough. Some days we go out there with all the instruments off because it is all safe water, but we are glad you enjoyed it and we are out to improve further to make sure that we do not become one of those _"so called sailors out there"_ 😉
Well done ladies one way to see after how well you have done set tracking on the plotter leave the sun cover on and you see just how well you have done. Practice will improve your skills. From a commercial captain 🧑✈️ you have done a great job. 👏
We have the same hand bearing compass. Electonics can fail so Yeap very important to be able to do it manually. But it also important to have up to date charts and lots of them
It is a worthwhile exercise and we feel it increases confidence in boat handling for when something goes "Whirr-clunk" and all the lights go out 😄 (Been there, done that!!!). Fortunately we have all the charts for Ireland, the Irish Sea, the Clyde and everything up to the Small Isles and lower Outer Hebrides.
Thanx for another great video. It was ages ago I used DR in navigation. I know that it is very easy to manipulate the GPS signals and to make sure to have a correct position the old style of navigation should be used if you don't have multiple gps:es. I don't believe that all gps:es will fail at the same moment. I have my plotter, the vhf, the ais and also an old hand held GPS. I always bring paper charts with me in my boat, but it is the plotter that is the main navigation for me. I mostly sail inshore in very familiar water and for 99% of time I don't look at the plotter. I read in YM years ago how to plot your position while sailing offshore. You should mark an way point in the GPS for the compass roses on the chart. Then the GPS gives you the bearing to the roses. When using a long ruler you get a fix very easy. I tried this on an offshore passage this summer. I got most of my fixes on my planned route line.
We also have multiple GPS systems aboard but the military interfernce would take out the lot of them. Luckily, this usually happens in familiar waters with easily visible landmarks but it was an easy YM exercise so we went for it. We did see the "waypoint in the compass rose" stuff and looked at our chart and thought _"that waypoint would be a long way out of our course..."_ 😄😄
Lovely to see you both on the water and enjoying yourselves! Beverley looking cool as a cucumber at the helm while poor Gaynor imitated a rabbit bolting in and out of its burrow! All the very best. James
Bev had it easy. All she had to do was stand there and steer, but at least I did not have to manoeuvre in the marina on a gusty day! We had great fun and we were smiling for days afterwards
Dead reckoning can be a very quick and accurate way of determining your position. (If you pick the right house LOL) All the RYA courses insist on paper navigation at the moment. Electrics can fail re.alternator, lightning strike etc. Nice video. Great to see the boat being used😏
It was great to be out - we really enjoyed it and we had a blast. The Dead reckoning was a good laugh too and we needed the practice anyway. Glad you enjoyed it 👍
Great job especially for 1st attempt. Excellent skill to have in your arsenal if the worst happens and electronics die. Another great reason for having paper charts. I just have to find the ones we bought for Atlantic Europe years ago but never got to use yet
We may do it more often just for the heck of it. You should give it a go, it's a blast 😄 Imray's C18 chart is a large area one that does Atlantic France for £22 / €25
Very very good ladies. Wondered why you were doing this. However it makes me think. I would love to brush up on chart navigation…but I’m afraid it’s been Navionics, WindPredict, tide tables…so that I can identify the relevant tidal streams and off I go. After my initial paralysis at times with owning and navigating a boat, I do increasingly find my self doing the right things. Great video and a great nudge! ⛵️
Have you swung your steering compass? Tom Cunliffe has a recent video that shows how to do it, this will give you your steering compass deviation which you will need when you start working out courses to steer.
We tried it a few years back and there was not a lot of variance. I suspect there is not really enough metal on the boat to be a problem. We have banned all magnets / phones aft of the companionway steps and in the nearby lockers. Everything is stainless which is non-magnetic (or nearly so)
Binocular with an integrated damped compass is a wonderful thing, we’ve that yellow hand compass too but it’s only for emergency use! Fair winds to you.
We too have the integrated bino/compass (you can see Gaynor wearing it in the first clip at sea about 8 mins in). We find them to be really great for looking down a bearing to locate buoyage or other obstacles. The yellow plastimo sees little everyday use, but we like having it aboard.
Luckily we CAN forget it. The difference between True and Magnetic north here is almost zero (the two were in alignment in November 2022 - this year the separation is about 0° 20'). Obviously if we go elsewhere we will be back on the CADET scheme!!! 😉
That is what we did for the first waypoint. The transit line was the RNLI station and a spire, the second mark was the house in Ballyholme that is marked on the chart. It intersected the transit.
Navigation is super important, i feel you are over complicating it, you have modern GPS use it, i sail to the wind to make passage and adjust accordingly, i use my hand compass to illiminate a collision, then use AIS as a last resort.
We do use GPS, but we have had GPS fail once due to electrical failure onboard and once due to military interference, also non-GPS navigation is part of the Yachtmaster syllabus so why not practice in a benign area?
@@pauldent7067I dont think that is a very helpful comment. As a sailor myself, I should say that the issues the ladies highlight are useful for all of us to consider.
All very interesting, commendable to refresh, go back to first principles, and highlight some of the realities, human errors. Can I point out though, this is not, 'dead reckoning', but pilotage, to obtain a 'fix' . However, Dead Reckoning, for example, is estimating your position, as in fog, or darkness, nothing visible no references, by using distance travelled, using log, or clock and estimate of speed, then correct for current, along with compass heading, corrected for leeway, deviation, variation. This is then referred to as an EP, Estimated Position, derived from all this 'reckoning'. Before GPS, and without Sextants, this is the only recourse to sailing far offshore, open water. All the same, really enjoyed your exercise, and candid way you share. Bless you. 🙏🏻👏🏻👏🏻👏🏻

We've always used a portland plotter. So it was good to find out how the parallel rulers work.
Have you not seen them before? Such fun using 18th century tech... 😄

I think the potential to run out of battery power is the biggest risk for electronic navigation tools to fail.
Cheers Ladies 😊
You're welcome as always Trev!

Great video ladies. I reckon you did very well for your first attempt and as you practice you will become even more accurate. Keep up the good work.
Thank you! Will do!

7:45 don't forget CADET ?

Love it, great episode. I must try that exercise when I get a compass and some charts. 🤠
It was great fun to do and definitely worth it in our opinion
Great stuff, Reg
Glad you enjoyed it Thanks for commenting 👍
If u have 2 marks in line u only need 1 more bearing to show where u are on the line
That is what we did for the first waypoint. The transit line was the RNLI station and a spire, the second mark was the house in Ballyholme that is marked on the chart. It intersected the transit.
Having two in-line gives you an excellent line, much more accurate to a compass bearing.
When you reduced the bearing to the chart with regard to the spire did you leave it at magnetic or convert it to true.? Just wondering
At the moment, the difference between magnetic and true is less than one degree so there was no changes needed.
Navigation is super important, i feel you are over complicating it, you have modern GPS use it, i sail to the wind to make passage and adjust accordingly, i use my hand compass to illiminate a collision, then use AIS as a last resort.

@@SailingYachtSaltyLass You put people off from sailing, tbh, its easy really most people can cope with it.
