I used to install security systems for a living about 10 years ago, and I remember a job I did for a clockmaker. On his work bench he had a maratime chronometer that dated back to the late 1790's. I was told that it belonged to a Ship's Captain, and it had been in his family for over 200 years, and even though it served no purpose on a modern bridge, he still carried it to keep the tradition alive. As both a maratime and a clock nerd, it made me so happy to see and hear the story behind it.

Hi Mike. I’ve been binge-watching your videos most of today! They’re awesome! However, just to clarify, the big iron balls either side of the compass binnacle are to compensate for the effect of the ship’s steel. There’s also a set of iron bars inside the binnacle that move up/down. Together, these all can be adjusted to get the compass calibrated. In trials they would’ve “swung the compass” through known headings, referenced against known points on land, so that they could get it pointing right. The wood etc. only helps make all that much better. Also, magnetic north is not actually constant; it varies depending on where you are. All the more reason for knowing what your instruments are telling you.

As a US Air Force Navigator I used a sextant to do celestial navigation on the C-130 transport aircraft in the late 80s-early 90s while flying across large spans of water (like the North Atlantic). Sometimes the moon was above the horizon during the day but if only the sun was visible it would give you a "line of positioning" and you were somewhere along that line. To narrow the position we used other means such as "dead reckoning" (involving a compass, a clock and an airspeed indicator). Celestial navigation can be very accurate.

Iron...not steel. They are properly called "quadrantal spheres", but more often go by the moniker "navigator's balls" in the Navy. Their positions are adjusted (during an annual process called "swinging ship") to reduce the amount of error introduced as the ship turns thru the points of the compass, as the ship's relation to local magnetic fields also affects compass accuracy. They are regularly put thru a process of heating to cherry red and then slow cooling (called "annealing") to remove residual magnetism. There are also iron rods called "Flinder's rods" contained in a vertical tube contained within the compass stand. These are for reducing magnetic effects from the ship pitching up and down fore and aft.

Olympic was the first ship launched and had all the fanfare and news coverage, hell most photo's you see online used for Titanic are phot's of Olympic. When Titanic was launched she wasn't really a big deal, she was basically just "the second Olympic". Same with Britannic, she got her fame from being a hospital ship that was sunk during war time. But before that, how many people in the general public really cared? Point is without their disasters few would probably even know of Titanic or Britannic as they'd most just be mentioned in passing as being "the Olympic's sisters" So if Olympic wasn't spared from the scrapyard, what chance would a barely known Titanic or Britannic had?

Hi Mike. It might be worth doing a follow up on this episode. For example I think your viewers would be interested in how the ships magnetic field was nulled out around the compasses. Something to do with those big red and green balls I suspect. There is history behind using a log to measure speed and keeping a log of the voyage. In the old days it literally was a log of wood thrown over the side and the number of equally spaced knots on an attached rope counted over a short time period - measured by a sand filled 'hour glass'. There's a lot more of course, I'm not sure how far (!) you would want to go with this level of detail - it's your channel after all!

Excellent video! To add a bit more to the Magnetic Compass section of the video, as a trainee (Cadet) Deck Officer, we learn how the various errors are corrected (with hard and soft iron) on the Magnetic Compass and it is quite an involved subject in of itself. Usually specialist compass correctors come aboard to do this job, the ship being "swung" in the process, but it can also be done by the Master if needs be/doing so can be justified. On contemporary ships the Magnetic Compass is mounted on the bridge roof, called the Monkey Island, or elsewhere high up in the forward superstructure to reduce the errors caused by the ship, a periscope being next to the helm position so we can use the Magnetic Compass on the bridge. We keep a book on the bridge with the Magnetic Compass errors in it as it is regularly checked, as we have to take this into account when navigating the ship. We tend to prefer the Gyro Compass when all is said and done though as it's more reliable, the Gyro Compass Repeaters being found on the bridge wings as the Gyro Compass itself is usually deep down in the ship, for example in the engine room. We usually have at least one permanently mounted Pelorus midships on the bridge.

I am also reminded of the wonderful book, "Sailing Alone Around The World" by Captain Joshua Slocum, who sailed his boat, "The Spray", eastward from New England, in 1895. He had bought a used chronometer, but it got drenched with seawater, so he boiled it. The minute hand fell off. He then used dead reckoning in his journey. It is one of the must delightful nautical stories ever written.

You do notice on the side of each compass the large steel balls painted red and green? These are movable and used to compensate for the steel of the ship and it's interaction with the magnetic compass. No matter where you place a compass on a steel ship, it will need to be adjusted and calibrated with a compass that is not in the magnetic field of the ship by using these steel balls.
@martinhonor3483
Жыл бұрын
Also the Flinders Bar mounted vertically in front of the binnacle adds to the compensation. A ship's compass is "swung" when the compass is compared to known bearings with the ship on different headings. Correcting magnets are placed around the compass bowl and the process repeated until all the differences (deviation) are reduced to minima. This is recorded on a card which is used to correct compass bearings to magnetic and true bearings. A quick and easy compass check when in sight of land is a "transit" when a bearing is taken on two objects marked on the chart are in line. The equivalent when out of sight of land is a bearing on the sun at sunrise or sunset. The bearing being a simple exercise in spherical trigonometry.

Gotta love the Titanic Honor & Glory dedication to historic accuracy: showing the Titanic listing to port slightly as she travels through the waters. I wonder how much of that port list was left on the night of the collision. The sources are not very clear on that. It's unlikely she maintained the same amount of port list throughout the (nearly) 5 days of her voyage, because a certain amount of the coal in the forward bunker probably had been used up for the furnaces and was no longer just shoveled from the starboard to the port side of the hold in the effort to get to the heart of the smoldering coal. Apparently coal fires in the bunkers were not uncommon. They often were the result of sparking when lumps of coal tumbled down the coaling chutes during the bunkering process. Sometimes the coal was hosed down with a water spray to prevent such fires from happening and avoid the formation of coal dust in the air, which carried its own hazards...

These navigation devices use so many different branches of physics and are very highly engineered with a high degree of precision, especially in the case of the chronometer. I imagine today it’s tempting to think of these contraptions as primitive, but I’d wager only a fraction of a percent of our ‘high tech’ population have an understanding of the concepts behind their purpose, with even fewer people able to work out how to use them. Not that we’re stupid; were they put back into regular usage, of course we would learn their operation. My point is they’re sophisticated, and in their day, only those specifically trained in their use would know how to use them; the vast majority would likely be as ignorant of the technology as we are now. I can imagine that most then would have been as in awe of these ‘mystery boxes’ as we are in awe of the computerized navigation infrastructure in use today. Heck, I’m in awe of my smartphone and all it can do with respect to navigation - including using it for celestial navigation! As far as how IT is constructed…well, I’m just glad there are those who know; I’m just at the level of being awed by a simple battery flashlight. :)

I would agree with J. Smith here. When I was trained in astronavigation in the 1970s our target time from observing four stars to putting a cross on the chart was 40 minutes, and that was using sight reduction tables, which simplified the calculations compared to using spherical trigonometry and versine tables etc. Also it is very difficult to take star sights at the dead of night as you need to be able to see the horizon. Star sights are normally taken during twilight when only the brightest stars (those used for navigation) and the horizon are visible. A dead reckoning position taken from the evening star sights seems probable.

Mike, about 10 years ago I got to see a copy of "Professional Mariner" magazine (American). They had an article about situational awareness. They said that one seldom repeated fact was that the crew was starting to " standardize the compass" by comparing the master compass to that in the binnacle on the bridge, perhaps to all others on the ship. This was required at fixed intervals by White Star regulations, perhaps by British Law. The oil lamp illuminating the master compass required trimming, lengthening the procedure. The crew was initiating the procedure when the lookout announced the sighting of the iceberg and elected to complete the procedure, then take evasive action. The implication being that they could have gently steered around the berg, steadied up on course again and then standardized the compass with the log noted as to why the procedure was delayed. Have you or any of the viewers ever heard of this story? The concept of ridiculous versus , well, stodgy could put it either way as to truth.

I'm going to go out on a limb here, but I'm pretty sure the "Time Sight" method was used to determine longitude. Per Dutton's Navigation & Piloting, this method was used in the merchant marine up through WW II. This method involves observing a known celestial body well to the east or west, noting the time of observation and the sextant altitude above the horizon, and having a good estimate of one's latitude. From these inputs one can determine the Meridian Angle, t, which is the difference in longitude from the ground position of the celestial body at the time of observation (note - one needs a current Nautical Almanac to determine the ground position). My guess is that Boxhall had a good time sight fix at evening twilight and his estimate of Titanic's position at sinking was based on Dead Reckoning (DR) since his last fix. At night it is very difficult to get an accurate sextant altitude as the horizon is very indistinct.

A few years ago, I was trained by the Canadian Coast Guard for search and rescue technique. Still we have to learn how to navigate without modern instrument. During the tranning at night, of course we have to encounter the Queen Mary 2......just to spice up our training. Let's said that I felt so small in my little inflatable boat just a few meter on her side.

Oh wow! I love your channel and always look forward to new videos. But I never expected to see my own home town! At 4:48, that looks just like Thacher Island off Cape Ann, Massachusetts, USA! We are very proud of our twin lighthouses, built in 1851 (originally 1771). There are two so that ships arriving from Europe would be able to differentiate Cape Ann from Boston Harbor. When they saw the twin lights, they knew they had only a little further to go. Great video! Thanks so much for making my day! 💕🙏💕

It really puts into perspective the incredible engineering and attention to detail that went into the design of these ships and it's nice to see the Titanic in a more general way than always focusing on the tragedy of her sinking. Cheers and keep up the awesome content!

Wow!!! Now THIS is the kind of video I've wanted for ages! I've seen the pelorus mount in photos of the bridge before, and always wondered what it was! I always assumed it was an ashtray or something, since it was 1912 and smoking was common, and I guess I thought the bridge crew would be chimneys considering how stressful their jobs must've been, but it seemed too high up for that! And now I know!! I wonder if any of that tech has survived or been recovered. Having the ship's chronometer would be just aces! And that patent log and submarine signalers are completely new information to me, somebody who's been reading about Titanic his entire life! That's astounding! You never stop learning! It's crazy to me that Titanic had such advanced technology over 100 years ago! But amazing! Thanks for another excellent video, Mike!

the compass on top of the Lounge may seem that was un the middle of the ship, but actually that wasn't the middle of the ship as many think. If u look at the distance from the 4th funnel to the end of the ship and the 1st funnel to the front tip you can see that the space from the 4th funnel to the back end is longer then the front space from the 1st funnel so actually the middle of the ship was somewhere after 3rd funnel

Fascinating stuff! I've seen one of Olympic's compass binnacles on display in the gift stop of the Molly Brown House in Denver, Colorado, of all places. It feels like some of the celestial navigation script pages got out of order or something though, and the question of how they navigated under cloudy skies was never answered.

I assume they would use dead reckoning as it is the if all else fails option of navigating. One of the commenters said he used dead reckoning as a USAF navigator in the 80's/90's which I find interesting. As for how to navigate via dead reckoning it is pretty straight forward. First off you need accurate charts of the area you are navigating in. Using those charts you then plot a route from your start point to your destination. Now you just have to follow the line you plotted. Well easier said than done. Of course you need a compass to give you a bearing but you also need a method to estimate the ships speed as well as a chronometer. It might go something like this for one of the plots. You start out on compass bearing 125 your plot line says you need to alter course to bearing 135 and continue on that bearing for 20 miles then head to bearing 110. A reading tells you the ships is making 20 knots so you know after an hour has passed on the chronometer you are at the point you need to alter course again. Repeat until you reach your destination. Hopefully.

@@evanator166 I'm familiar with dead reckoning, or as some pilots say "If you reckon wrong, you're dead!" The question is how accurate that would be in a storm (for either ship or aircraft) as maintaining a steady course/heading and speed would be difficult when being battered around by wind and turbulence or waves, and unless you know exactly what the wind or current is you don't know how much you're being carried off course. That would still put you vaguely in the right spot, but I wonder if they had a more accurate method? Later there were radio-based navigation systems like LORAN, NDBs (Non-directional beacons), VORs, and later GPS, but not in Titanic's time - was there something else they had at that point though?

Super-precise chronometers for this purpose, and their evolution, could be a fascinating video in itself. And it's an ongoing effort in present day, now trying to make extremely accurate atomic clocks that can survive a rocket launch for use in satellites and space probes - the same challenge for the same purpose but in space.

Simply stated, the chronometer keeps track of time at a reference point...which for centuries has been the Naval Observatory in Greenwich, England. Greenwich has been "ground zero" for timekeeping since I dunno when. Once upon a time there was a "ground zero" reference point established in the celestial star sky... a point from which all other stars were measured. This point was called the "first point of Aries". Think of "Aries" as the locomotive on a train that circles the Earth, and all the stars are "passengers" in the following cars. There are 24 cars. Now, all stars have been given "seats" and seat numbers in 24 cars behind the loco, based on a their relative position to the loco "Aries". A star might be given seat number 1 in car number 2. Another star might have seat 2, car 2...just behind the first star. You can now locate any star's position on the train by knowing it's "seat" on the train and by simply consulting a "seating chart". Now, as the train stretches ALL THE way around the world, the locomotive sitting at the station in Greenwich, pointing west... the end of the train is also just in FRONT of the locomotive (being as the train is sooo long, it circles the globe). Now, the train then leaves Greenwich, heading west (actually, the Earth is moving East, under the "train".), locomotive "Aries" at the front... It travels at a constant speed, and always west. It NEVER stops, and it circles the Earth every 24 hours. If you know how long it's been since the locomotive (ie first point of Aries) left or last passed the station at Greenwich, you can calculate not only where the loco is on it's journey around the world (called the "Greenwich Hour Angle of Aries"), but you also have a good idea of what the "passengers"(stars) can see from anywhere on the train (ei where THEY are as the train travels around the world). Example: The locomotive "Aries" is now 12 hours out of Greenwich. Coincidentally, this is actually on the exact opposite side of the Earth from Greenwich, the Earth being 24 hours in "circumference". Let's say it takes an hour for each car to pass over our heads. Let's say star "X" is in car #4, and star "Y" is in car #6. Someone looking up in the sky over an area 4 hours west from Greenwich would see star "X" passing overhead. 2 hours later, they'd see star "Y" pass. Thus, if you know PRECISELY how long it's been since Aries "left the station" at Greenwich, you have an idea of what stars you'd see overhead, based on an estimate of where you are. WE use the difference from what we "expect" to see and what we ACTUALLY see to calculate longitude (longitude is actually a measurement of "time" from Greenwich, converted to an earthly distance, Greenwich being on 0 longitude). Let's say it is exactly 9 PM GMT (Greenwich Mean Time). You have looked on your seating chart and expect to see star "X" passing directly overhead. You step out onto the deck and look up...but find you have to turn to the east to see "X"...and see "X" is just now rising above the eastern horizon. In other words, "X" hasn't "gotten to you" yet. Now, you KNOW the time is correct...so it must be your ESTIMATED POSITION that must be off. The difference in where star "X" actually is and where you THOUGHT you'd see it...based on an accurate measurement of time to locate where the locomotive "Aries" is around the world... is converted into a correction you apply to your estimated position to get a corrected longitude. If you do this correction, and recalculate your expectations for star "Y", you should see star "Y" appear "right on time". Again, the key to the whole thing is knowing where "Aries" is... and you know this by knowing the time in Greenwich. This is, of course a great simplification...and assumes all stars pass directly over your head... but it illustrates how we keep track of stars and rough longitude. We actually do this sort of "recalculating" all the time. If we know that at 6 AM our alarm clock is within a straight-out arm's reach, it really doesn;t matter WHERE the alarm clock is the entire rest of the day or night...as long as it is where it is supposed to be at exactly 6 AM. It COULD have travelled all the way around the world! If we have to reach UP to turn it off at 6AM...we've know we've fallen out of bed.

Awesome video. Showed my family this to help explain what I do for work and how ships crossed oceans before GPS/LORAN. It wasn't long ago (almost into the 80s) that ships were still relying heavily on celestial navigation. On an overcast winter north Atlantic crossing, it was common for ships to make the crossing with getting few, if not any accurate celestial fixes (positions) for the entire voyage. Also, the submarine signaler. Holy Sh*t. Im shocked I know nothing about this considering how much of a nerd I am with this stuff. Great research. For somebody who hasn't done this for a living or had gone to school for it, its impressive how good of a grasp you've acquired on all of this. Its even more impressive how you've put all of this information together in such a digestible and easy to watch video. Thank you!

The engineering around magnetic compasses is so fascinating for such ancient technology. They're still required equipment on airplanes today even though they've been made redundant by radio navigation and GPS, and airplane designers have come up with all kinds of clever ways to isolate them from interference - in most small airplanes they'll be above the windshield away from the other instruments, but my favorite are the DC-9/MD-80 airliners where it's mounted on the back wall of the cockpit and has to be viewed through a mirror. Funny to see that shipbuilders 100+ years ago were struggling with the same problem.
