00°00'00'' [Uma Daily #7] 

6:34 That red ball on the pole on top of the observatory is lifted up and then dropped at 1pm each day so that ships leaving the port of London can set their chronometers. It began in 1833 and is STILL DOING IT TODAY. How cool is that? I live just across the river from Greenwich and cross the prime meridian twice on my journey to work. That's four changes between east and west hemispheres each day. I know it's an arbitrary line but it still makes me smile when I think of it...

Track down a film called ‘Longitude’. It was made by the BBC I believe, and tells the story of the development of a clock they could take to sea and use to calculate Longitude. It’s a story that made sailing great distances possible. You were right outside the museum that houses those clocks. They are super impressive.

I used to live only a few hundred metres from the Prime Meridian and I used to walk the dogs in Greenwich Park (and used to cross the line every day when I went to work). I haven't been in the Maritime Museum since the 1970s or 1980s despite living so close. I guess we were lucky that we lived so close, but it was so 'ordinary' for us. It's only when you see this through the eyes of a tourist/foreigner, that you appreciate how special that it is.

Ahh good old Blighty! Rich in history wherever you look! Britannia ruled the waves for quite a while 🇬🇧👍

Very short trip to London. You will have to get back sometime soon to see and enjoy London. Next time maybe 3-4 weeks. So much history.

I've been following Uma for about a year now, and I would say this may be one of your best vlogs. Thanks!

6:55 It's the time difference at noon between where You are and Greenwich that gives You the longitude, not the time You have been traveling. love your vids +1

The Greenwich Meridian runs through my town in southern England, next to a stately home, called 'Meridian Hall', just 10 minutes walk from my house. A cool place to take visitors. ;-)

You guys know how to make a good blog with good and interesting footage! Thanks very much for traveling with you. Highly appreciated!

It's been so nice seeing you two every day! I appreciate all the extra work you've been doing!

I'm sure I could get lost in this museum for days looking at all of the cool items they have displayed. The time lapse Prime Meridan👍. Thank you for taking us along for this magnificent journey. I'm going to miss your daily vlogs.🥂

That was really fun! I can't believe the quality and story telling! Off the charts! Daily or not. You two are amazing! And I learned some fun stuff!

During our trip to UK last May the Royal Observatory was one of the sites I did not have time to see. Next time! Thanks for the visit.

Guys. We recommend a film called the "Search for longitude", we think it's a BBC film? It tells the tail of Harrisons development of the marine chronometer. All mariners should watch this film and see the devotion this man and his son undertook in pursuit of the development of a time piece accurate to establish longitude. BTW those buildings on Canary Wharf behind you. Ant was involved in the construction working with the architects and builders. He's to modest to say so but I am so proud of him [Cid] Sail safe, Ant & Cid SV Impavidus. xx

So glad you were able to enjoy our country's history, to many of us it means a lot. You will always be welcome here.

And no batteries required ! Awesome 👍 !

It is very interesting seeing your reactions visiting my country and your visit particularly Greenwich and seeing the Prime Meridian.

The National Maratime Museum is fantastic - and the Meridian is very cool too - did you see the ball drop at noon (for the sailors to set their clocks to noon)? The planetarium is really fun too! Wish I'd know you were here - you would have been welcome to stay!

Guys the daily blogs worked out well, it is something that you should use more often especially when you are sailing around the Mediterranean.

Going to call it a day , was the phrase I think you wanted , it sure wasn't a night . I am very glad you seem to have enjoyed your visit to England , where most of the planet was mapped from thanks to Mr Captain Cook . The M and r stand for master not mister in his case . I think it was some crazy amount like a third of the world he mapped for the first time . He heralds from Yorkshire up to the north of England . Please remember there is much , much , much more to England than only London. I am certain you will recall standing upon the line as your adventures take you places in the future. You will be moving in the footsteps of great men who were fuelled mainly by grog , and fear of the lash .Where ever you travel may the times be good ,thanks for taking me on a trip of places within my country, appreciate it . All the best. bon voyage.

It might surprise you to learn that the Prime Meridian may change soon to the original 'Rose Line', that which runs through Paris and Roslyn Chapel in Scotland (made famous by the novel and movie 'The Da Vinci Code'). I hope you guys are heading north, if so you can pay a visit to Roslyn. After all, Harry Potter's Hogwarts was in Scotland!

brill vid 00 00 00 how many sailors can say they have stood at the exact location u should make a plaque to fix in uma {:-) PAV

I went to an Adam Ant concert at The O2 in Greenwich . We saw the line there.

THAT museum would capture me for days !!!! thanks for taking us along !

I was at the Royal Observatory several years ago. at the time they had a big exhibit about Watches, and how the accuracy has improved over time (no pun intended). as part of it, they were testing people's watches to see how accurate they were, and giving little certificates to say how accurate your watch was. I had mine done, and was proud to know that mine was the least accurate they had seen all week :)

So great to see you in England, we've watched you sailing all over and love your adventures. The Meridian Line you were standing on goes right through the shuttered building behind you and through the middle of a huge telescope that was used to fix it's position. The telescope is set in stone blocks, its a monster and (for it's time) has a staggering accuracy. Love the videos always fun to see what you've been up to.

Thanks for the video,i have not been to the museum but it looks pretty cool so that's on my list to visit

you guys are very fortunate to travel in all way of transportation and see things that many people will never see in a lifetime,

You guys rock. So impressive how well you spent your time in UK. Will miss daily installments, but totally understand how tiring they must be. Safe trip home to Uma.

You guys are great teachers. Best video on RU-vid. Love the time lapse.

I live walking distance from here. Theres a bunch of cool moorings walking distance from here, Greenwich sailing club is over 100 years old, they have pontoons and buoy moorings. St Catherine's docks is not too far away, its an amazing place, right next to Tower bridge and the Tower of London. How come you didnt sail to London

My goodness - such a well made video. So Cool!!!!!!!!!!!!

So awesome! I’m excited to see some of the places I’ve been. Thank you guys so much for all the daily vlogs! I’m going to be in withdrawal when you go back to weekly posts.

Thanks for the story. If I ever get back to London, I will definitely check the museum out.

so down to basics we the british can tell the world when they can wake up and when they can go to sleep lol

The prime meridian is the arbitrary line of longitude which by measuring time away from this 0-degree line you may calculate 'your' longitudinal position based on 'your time of day but not your latitude.

Great blog; just scanning through some of the comments to see whether John Harrison gets a mention. He is responsible for devising a method of plotting longitude while at sea with his development of the sea clock/watch. Check out Longitude, a great book by Dava Sobel American author, about John Harrison's struggle to convince the scientists at The Royal Observatory that his clock was the solution to accurately plotting longitude.

At :40 is where I proposed to my wife (very top of the London Eye) if she said NO I could jump and all would be good! 🤣🤣

Excellent vlog! Thank you for sharing information on the museum and prime meridian line. I had no idea it runs through London.

Another great job of teaching and sharing fantastic sights and information 0---)

Really enjoyed this episode!! Would love to visit there someday and check out the Maritime Museum. There is a really great book about the invention of the first accurate marine clock it is called " Longitude" bu Dava Sobel, it's a must read IMHO

a very interesting few days in the UK Love your videos well done you two you make everything seem easy to understand and very refreshing !

Sweet you set your clock from the river when the red ball drops, that hill is where little me used to sled 🐳🐳🐳

Glad you had a great day in my home town. Love your videos

Loved it.

Thank you, I had always wondered about the how and why of the meridian line.

Hey you two - another very nice video. Some shortcomings in the sound make it even more lively! Thank you for that.

Nice video and enjoyed a look in museum

You can the film about the Harrison watches on RU-vid it's called "Longitude"

In 1976 I stood in the same exact spot. How cool is that?

Get sailing😁😍😝

Those are chronometers not clocks. Be sure to have back up GPS. :)

Nicely produced

I was there 4 yeas ago. Great place to be. Nice park too.

Enjoyed the Meridian time lapse.

that was educational thanks

Love this vlog. Really liked the time lapse shot at the end. I know you felt silly standing like that for 10+ min.

Brilliant

7:35 - That squeaking sound... LOL New nickname of "Squeaka". :-)

So... did you buy a watch and set it to the Prime Meridian time?

How come Kika doesn't know how to say "meridian"? : - ) Beyond that, I have loved that you guys have taken us on your trip to the UK (and to the boat show)! I found the mini series on Harrison's development of an accurate chronometer to be truly fascinating. So seeing the "clock" display at the Royal Observatory was truly great! Thanks.

Great Job Guys! It's nice to finally see where I've been setting my Boat's GPS off of #GMT #NicePlace

Some more information about the Zero-Meridian? It is an artificial, human made line, which has not always been situated in Greenwich/London. In former times it has been in Roma and Paris as well. Every strong sailors-nation requested it for the glory of his own country. In fact it could be on any vertical line between north- and south pole. It is situated in Greenwich now, because its opposite line - which marks the 180 degree line - on "the backside of the world" is used as datum-line. This 180 degree line is not touching any land or important island. And it lies exactly between the asian and american continent. So it is clever to leave the zero-meridian where it is right now. Nobody has to live in a country where it is tuesday on the eastern and still monday on the western side.

Call this “Fin!”

Thank you for this Video, I've enjoyed the Dailies, though I can understand that it would be impractical to do them all the time. When you sail to the UK, please call in at Falmouth, Cornwall and visit the 'Other' site of The National Maritime Museum, you can moor up right next to it, or there are some really good anchorages close to.

Safe trip guys hope you had a great time over here

Great episode :) Did you know there are plans afoot to abolish or move to France the Prime Meridian, seriously hope you are as shocked as I was !

Actually guys, it's currently British Summer Time, which is an hour earlier than GMT. Also called Daylight Saving Time and various other verbal gymnastics. Fortunately, the guy that campaigned for it to be introduced died before it happened, as he deserves to be shot. They stuffed around with the time during both world wars, but all of that was subsequent to the establishment of the prime meridian and the use of proper, British winter time, GMT. Hopefully, if we ever do manage to escape the greedy EU's grasp, we'll be able to revert to GMT again, as the only beneficiaries are farmers, ie, 1% of the UK's economy. The rest of us have been robbed of an hours sleep a day for half of our lives just because they're incapable of sorting their own watches out without damaging the entire country in the process. What's the point of being an IT consultant if you can't have a lie in every day?? Anyway, come back in winter when GMT & the Prime Meridian revert back to meaning something. PS Love these vids, thanks for the extra effort you've taken to do a daily vlog but really, you should chill now for a bit. The strain is too much :-)

great TIME Lapse

Come to Norway!

Really enjoyed that, but, as commented elsewhere, there is just so much to see and do there... perhaps another day sometime to punctuate the sailing. A word of warning... your blogs are so good that you're going to put paid professionals out of business!

fine video work! you may have given me a reason to visit london!

Great title.

come to gloucester while your here id love to meet you guys

00 00 00 is not necessarily where the line is, it all depends who is looking - for more detail, this is worth a watch ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DmvHZ4omB2A.html

awesome vid!

Did you go down to see the Cutty Sark?

Did you check your GPS bet it was out by 100m to the East because of the datum shift

Did you see the ball drop, or did you take your eye off the ball?

First glance at your thumbnail and I thought you were standing over (minding) the gap!

Dam I forgot -- Calm hair day today congratulations looks great.

Time is a human construct. It's still cool to stand on the axis datum point though. It's an OBSERVATORY, did you think they'd put it in a ditch? ;P

Diggin it

When you were standing on the line did the GPS on your phone read 0º 00'00.00" ? If not, could/did you reset it?

I always thought Nelson's blooded shirt very arresting.

Prime Meridian sounds like a steakhouse where they do a good surf n' turf.

2 love your vids

Did you visit HMS Victory?

In addition to some sketchy information as noted in the comments below, you have to work on your lighting for some clearer images.

very cool

Are you going to see HMS Belfast ?

👍🏻☀👍🏻☀👍🏻☀👍🏻

I thought it would be bigger.

Nice day yo ho ho and a bottle of rum tonight chears

Ok yes you need more gold leaf on uma, note british at its best with the speed boat record, not forgetting GMT at the royal ob serv , dam we brits gave a lot to the world from such a small dot on the world map , hope after we excape the clutchs of the europe we once again can be as inventive as before. Seems realy strange seeing you in my birth country ,London is such a small part of it.and most english stay away from our capital city believe it or not.

I may be wrong, but I understood it is the mer-id'-ian line, not the mer'-i-dan line, Kika. But you're so dang cute, just saying it the way you do... you're excused... ;)

UMA is missing you two i bet....

So it is flat!

live free sail hard
