oh god as a deck cadet, this the most helpful, clear presentation of tutorial i've seen in youtube. You should be my professor. lol subscribing.
Have you ever tried out the Diginav Nautical Charts system?
Thankyou for the vid.
It was well explained and easy to understand
Might even go buy a boat 😁
I always wanted to learn navigation even though im not a mariner. Thanks
I don't know any better explanation.Great video!Thanks )
Thank you for your kind comment
Sir, May i humbly ask how will i know if my chart is E or W or N or S?
@@gerald8095 on the compass rose?
This was terrific - just at the right speed...clear and put in terms even I could understand! Thank you
This is an amazing amount of information presented in such a masterful way of teaching. Pretty much everything anyone needs to know about chart plotting with the exception of Course To Steer, which Captain Dave Medeiros presents on another excellent video.
This is a really an excellent tutorial on chart navigation. I love collecting maps (cartophile, if I may put it that way) and am passionate about manual navigation (using compass + maps for groun navigation) without the aid of an electronic positioning equipment (GPS). Though, I am not a professional or an amateur seafarer, still I wish to learn about this in more detail. Could you please tell me, where I can get the nautical map from, the one like in the video? Also, I would like to know from where one can get latest information on the ocean drifts for a particular location?
Thank you again for this excellent and lucid video presentation.
Try richardsonscharts.com. Not sure if you'll find what you are looking for but they may help. Caltopo.com is a free topographic map download site for land and they may do navigation charts/maps as well but not sure. Has to be free download sites for what you are looking for but...good luck!
I was able to find some free full size maps by placing a want ad in a local online service (similar to Craigslist) A fellow that salvaged boats had plenty of them. They may be out of date but work well for practice.
This intro tutorial was absolutely the best and simplistic demo of basic navigation I have seen. Great job and thanks for taking the time to video and post this superb example. What a fabulous resource you are.
This man is a great teacher. I've never learned well from books, the steps never seem to line up in my head, but when this gentleman teaches anything about navigation it makes perfect sense.
Yes I agree ☑️
The best explanation ever. Thank you
The best presentation of concepts I've seen so far. Thank you!
Such a thorough and clear explanation. Thank you so much for this great video!
Speed = la-ju
Acceleration = pe-cu-tan
I quote from textbook.
You are a very good teacher. Thanks for sharing your knowledge
This is awesome! Clear, straightforward, and well done. Great job!
This explanation was awesome! Nothing better than having someone demonstrate the logic on the Chart it really helped cement the process!
World beautiful explanation I don't have seen ever like this explanations.
I watched the video and wanted to subscribe.... But oh no, I already have subscribed....just watching the sake of understand the navy movies....great teaching style sir.... Love from India
Thank you
Can i ask what kind of rulers is used in that video, I am a new Maritime student I need this badly
Thank you for making this video really helped me.
Thank you for the video, could you do one on tide and current problems.
TIM King Thanks for the feed back. We will try to put together a tides and currents video for sure. We are always looking for suggestions.
Great video! I don't think an explanation can get any clearer than this! Thank you!
Love it, too, but I got confused over what appeared to be as measuring distance with the dividers on the horizontal scale...I thought you cannot use longitude to measure distance. I'm preping for ASA105 this coming weekend and I don't even sail YET! Someday.
Thank you for making this video. Great job.
Thank you so much. That made my neurons connect, ha! Testing tomorrow so I really appreciate you.
Very interesting and exciting!
Why in school so complicated, but here in youtube you can understand for only a minute. Great explanation.
that's what we provide in our college :)
At the beginning I didn't know anything about navigation. However by the end I know how to calculate how far, at what speed, and how long it took me. It did help I knew the words he used.
Thanks for the video.
Dammit.. thank you. We the maritime community thanks you for taking the time to educate us.
This man is a genius. He is such a great professor. Im in the navy and I love reading about navigation and learn about maritime history and this man makes it so easy.
Very simple and educational. Thank you very much.
The best, clearest and cleanest explanation.
I'm not a navigator but this is helpful in any ship navigation technology designer.
Yes please, a video on tide and currents, speed through water and speed over ground in radar , wind and current effects on ship STW and SOG
I watched this video for 8 times
Great information thank u so much professor for the amount helpul explanation. That is kind of u Sir respectful greatin from us all.
Oh yes, subscribing too. Very helpful and very clearly explained. Thanks.

Don't understand why you would not set a course to steer unless the tide info is not available. Basically the boat is 1.2 NM off preferred course.
According to Bowditch the term Course Made Good (CMG) is a misnomer. More accurate term is Track Made Good.
I guess that makes sense since your CMG is always Zero unless your Set & Drift and your Leeway is perfectly in line with your Course Line.
An excellent video for anyone trying to learn about position fixing - thank you!
You make everything so easy to understand 🙌👏
Excellent video
Thanks a lot mate
Is the scholarship given real?
If it so no country in this world would be safe.
This was really clear to a complete beginner, thank you
COME CAPIRE DALLA DOMANDA DELL' ESERCIZIO CARTEGGIO NAUTICO istruzioni specifiche per capire quale tipo di conversione è richiesta RIFERITE ALLA FORMULA/E DEL TEMPO; X CALCOLO SPAZIO , TEMPO , VELOCITA??? LE grandezze fisiche CHE sono coinvolte MIGLIA,NODI, TEMPO SIA IN MINUTI ,CHE DECIMI DI ORA ?
I invite you to check on our website : nmi.edu/
Excellent explanation. Thank you
Excellent
Fantastic video. Thank you.
This made it soo mch clearer how to plot thank u
BEWARE OF ERROR
at 7'28' he states this is the course over the water. This should be COG (course over ground)
WRONG. Good thing you're not a captain.
marking is not really exact, sometimes there is confusion in the terminology and all the calculations do not belong on the map. messy.
good tutorial so if you can work out drift before and alter direction to compensate you could have been at the position intended setting was 90 degrees but drift caused a 107 degrees heading 17 degrees of drift so you could set off 73 degrees course instead of 90 and you be on track for intended position after 45 mins ? never done chart plotting before but its interesting
Huge hug! You may have just saved my life. GOD bless you.
very helpful. :) can you make some different sailings? like parallel sailing and etc? thanks. :)
Great video, I think us Brits use different terminology for drift and set, drift being experienced tidal stream and set being estimated position - does this sound familiar? Thanks for the great video.
This is not Brtitan. We kicked their asses out in 1776.
2:15 when you just write on the chart - do you need to rubber it every time you use it again?
Plotting rule number 1: erase everything you dont need so it wont confuse you in the future.
@@nativeafroeurasian Stap asking stupid question.
where can I buy charter plot maps at
Very interesting never new how that was done. Honestly after watching I still don’t ;). Who wants to go sailing 👍🏻👍🏻
The best, clearest, simplest explanation I have found. Thank you!
How do you plot on harbor charts. The smaller scales are easy the large scale I have problems with
Very good video. I thought drift the was distance the tide has pushed you, rate was the speed of the tide and set was the angle the tide is pushing at?
So now the next step is Course Correction to maintain course to destination, correct? Is this 'course to steer'?
Thanks for the lesson.
grt video sir ....... very helpful learning chartwork
Happy to help!
@ 6:50 divided by our speed .75, should be divided by time .75.
Amazing explanation! Thank you
I don't even own a boat and this is intriguing!!
You dont need a boat for this to be useful. It also works with your private jet.
@@obiwanfisher537 O yes. Got 2 of those!!
Have been searching You tube for some info, and suddenly - God of Random gave me Your video. And i Would like to say - inspite of it is good educational video, Your voice is making the BEST ASMR Session EVER. Continue same way. Thanks and Best regards.
thanks i actually understand you! :) even im a 16 years old.
Zentopia GROWTOPIA same here
Has anyone tried out the DIGINAV PC system? Just google diginav nautical charts.
Amazing video, great presentation...Thank you Master Chief.
Excellent! Making simple what others complicate.
Enjoyable video. With electronic charts and GPS / Chart plotters some boat owners never utilize paper charts. I always liked having them on the boat.
Thank you for the clear and helpful explanation !
Great! Thank u so much.
Your are welcome!
You are good, how do you fill a chart correction table
thank you sir. i learned a lot
question your speed is Knots - but your measured in miles ? A Knot is 1.15 miles ? Am I missing something. However your explanation is very good to me. I appreciate your explanations.
When he says miles he is referring to Nautical miles. 1 Nautical mile = 1.15 Miles.
he is using actual miles, not shit miles.
Oh my gosh I have this school saved booked marked, lucky for me? Any chance of me getting familiar.
This is WRONG!!! because you measured distance on the longitudinal scale. You CONNOT measure distance accurately on the bottom or top of the chart- only the sides. people fail tests because of this simple mistake. uhg
A Wass ... he is acually measuring the distance in the left side of the chart.... on the latitude scale... where do you see him taking the distances on the longitude scale?
The latitude of The Earth is vertically going to the Poles from the Ecuator Line and the longitude is horisontally going to East or West from Greenwich... which is the prime meridian of Earth...
So, in my oppinion there is nothing wrong with his method of taking distances because he is taking it on latitude scale not longitude...
he did. im just too lazy to find it but he did took a distance from longitude scale
@@loneranger1646 At 4:30 he was transfering a known latitude GPS coordinate, not measuring distance.
some one , help please . Where do I get my hands on charts like he's working with ( I'm in jacksonville ) ? I would like paper charts to plot my course 's for this area .
Is a sailor's medical examination difficult? Are the requirements for passing difficult? How many times a year do you need to take it?
A very gppd explanation. Thanks. Back at the basic math haha didnt think Id ever solve problems like that in real life, but here we are.
Thanks for a perfect video
At point 6.45 in the video you say to finding the speed and you take the distance divided by the speed, yet you use the .75 figure of the time? to get the speed? I assume this is a verbal error, as you already have the time and are wanting to find the speed.
txs alot for your explaining .You are very good teacher .
I´d like to ask one thing , what are the lines that exist over the map , apart fromLat long I see more lines
I know a 3rd mate and he says he gets paid a lot for a job that he says isn't that hard. He wasn't kidding. This is way easier than land navigation for sure in my opinion. Everyone Ive spoken to in that field loath celestial nav and rules of the road over anything else. Plotting is actually considered the easy part.
Our profs in academy learn from this guy. 👍🏻
Very helpful. Thanks
how to plot when you have a given of distance and bearing?
does this bring back memories HAYDEN MEMORIAL CARTOGRAPHY ROOM
Should't this Set be corrected by the actual speed, which appears to have been more than 5kts? I'd expect a circle segment to be drawn, with center at start position, that crosses the DR. Think about it: If the real speed would have been 10kts, the tide flow calculation would be completely wrong, which to me indicates that this method is not correct.
You forgot to convert true north to magnetic north there cappy.
This was really fascinating and enjoyed learning from you.
so with this could you turn the vessel into the current to counter it just like crabbing in aviation? or is it completely different.
