Navigation - Dead Reckoning (White Board Part 1)

Capt. Dave Medeiros explains how to determine your Dead Reckoning course after being given a known position and time.

Navigation Plotting is an essential skill for working in the maritime industry. This video is an introduction to some of those concepts. If you've spent lots of time on the water, but have not pursued a professional license, you should consider yourself a candidate for an Operator of Uninspected Passenger Vessels (OUPV) 6-Pack license. This license allows you to charter vessels with up to 6 paying passenger and is the first step to a career in the maritime industry, full-time or part-time!

Dead Reckoning: If i had to use this math at sea - i reckon i’d be dead.

This is the kind of college lecture I imagined in my childhood. TT

[@김송-l1i]

he is way better than college professor

[@daylaanguerra9620]

Yes. In fact, teaching is part of being a seafarer. On board, when you go to sleep, you need to trust that newer officers know what they´re doing, so you teach them, as you learn from more Senior officers.

This chap is very excellent 👌👍😊👍😊

[@Vijaykumar-sd9ol]

I watch this video because i saw mission impossible dead reckoning trailer and curious to know the meaning thanks 🙂

[@movementvocabulary]

Haha! Same

[@Entrenamientonautico]

But remember that it's 'ded' (deduced) reckoning!

Many thanks from the United States Naval Academy

This keeps coming up as circular logic. If you are on a fully functioning boat with chronometers, short wave radio, GPS, etc, etc, etc, of course you are going to know your fixed position. From that you can calculate the bearing, heading and speed to determine your current position. If your boat sinks and you wake up in a lifeboat several days later, circular logic is useless. If you don't have a fixed position and don't know an assumed position finding your location from a circular logic approach isn't going to work. Accurate navigation was possible and done after the invention of the chronometer, the magnetic compass, the sextant and navigational charts. This was centuries before the inventions of short wave radio, the gyro compass and GPS. Passing an exam and surviving under adverse conditions in the absence of modern navigational equipment are two completely different issues. There must be a way to know your location and head you craft back to land without the information provided from modern equipment.

My grandpa used this same method during WWII, and went on to teach others the process. Seeing this long after he’s passed I feel like I’ve grown closer to him while still learning something amazing! Thank you

[@alainbuerom8635]

very, very Good teacher indeed! thank you Captain Medeiros.

[@caddeboy]

Thank you so much Captain.!!!! Regards from Turkey.

Thanks Captain , easy and amazing

[@SoloSailorDave]

Refreshing yourself on DR would come in useful if some country detonated an EMP weapon in the atmosphere or the GPS satellite network was knocked out.

[@133289ify]

Something FISHY is going on with the units of measure

[@angeloilustrisimo3685]

Sir how about the time occur was 0900H and after 1145H what will be the distance?

[@johns1693]

Thanks bro!!

[@pujaNNN]

Thank you sir!!!!!!!!

[@roseukin4111]

Thank you so much! This will surely help me pass my math exam tomorrow

[@lloydaldrenlabisig1603]

Love how it was explained. Thank you sir!

[@svkoukla9842]

Clear, concise--thank you for posting this.

[@joshuaespinoza2567]

Excellent teacher! Thank you

[@vadinhoafonso1585]

very clear in fact super clear

[@gordonblunt1506]

Amazing thank you ❤

[@farqfarq2225]

Excellent fellow , very good

[@moslemmaniavi4748]

Thanks captain 👏

[@voncastillo6432]

Thank you for your explanation 😊

[@vickarmazinas2676]

Short and to the point. Love your videos

[@keithisit]

I was expecting a knots to mph conversion.

[@keithisit]

Never mind nautical miles smh

[@jambarajan]

Thank you sir! very easy explanation!

[@martinapuleni2357]

You the best captain ❤❤

[@candiceb1978]

He sounds a lot like George carline to be honest

[@Adam-hf7hn]

this is how you teach. slowly and from the basics. no assumptions that we know anything. This way no student will feel left out

[@noor.a1459]

You're a good teacher

[@AdventuresInMetalDetecting]

Great explanation, easy to follow.

[@rogerdodger8813]

If you veer of course say go north, you need Trig. for Right an non right angled triangles. You surely need calculator on board. In the old days they probably used those books with tables. Thank god for GPS!

How does this one seems so easy yet in our online class it's very confusing/....

[@sto2779]

Your class room seriously needs noise cancelling panels. Your echos bouncing in the room is extremely annoying.

[@markbryanceralbo5646]

What is the GPS FIX SYMBOL, VISUAL FIX AND RADAR FIX SYMBOL?... TNX

[@satyaadevmishra8277]

sir kindly upload a video regarding how to calculate beam bearing and beam distance thanks

[@tthurricane8624]

dead easy concept but explained at 75%...:))

[@itservicemanagementmentorltd]

Thanks

[@vinodbhosle2674]

Well explained🙏

[@xiancodm2817]

Study ni kuya

[@kayang-kayavlogs496]

Great video 👌

[@natsbuenviaje2282]

thanks, cap

[@حارثمحمدناصر]

Page 561
The development of flight instruments made it possible to navigate airplanes by dead reckoning, without the need for being able to see landmarks.

[@حارثمحمدناصر]

But this method is no longer generally used because errors in the functioning of the instruments and changes in winds aloft make it unreliable.

[@sambbk9225]

Thanks Boss

[@grotyyachty1]

I thought the symbol for dead reckoning was was just the small line with no half moon in it.
