Transit the Panama Canal.

Our original itinerary we were supposed to calling into Curacao but with the invasion of Venezuela imminent the itinerary changed. Because of Maritime law we had to call into a port outside the North American coast to be allowed into the USA so we went to Cartagena in Colombia for a two hour stop despite no passengers were allowed to leave the ship. That was ok but disappointing we could not get off as it is a beautiful city but very hot in fact it was sweltering while we were there. We then headed towards the Panama Canal.
The Panama Canal.
The Panama Canal is a man-made structure that cuts through Panama 51 miles long. Before it was built ships used to have to go around the Cape Horn which was quite treacherous & added several weeks to a journey not to mention having to pass the hazardous Drakes Passage, Straits of Magellan & the Beagle Channel.
France started to build the Canal in 1881 but due to engineering problems & the high mortality rate of the workers stopped in 1889 after 22,000 workers died through accidents or after catching Tropical diseases such as Malaria & Yellow Fever or being bitten by venomous snakes. In 1904 the USA started to build the Canal finishing 10 years later. The canal opened in 1914. The manmade Gatun Lakes were formed to help conserve water.
There are three sets of locks Starting at the Atlantic/Carribean side The Gatun Locks raise the ship from sea level up to the Gatun Lakes 85 feet above sea level. This took roughly three hours to pass from the Caribbean to the Gatun Lake. The ship carried on through the Gatun Lakes to the next set of locks which help lower ships, called the Miraflores locks (& New Cocoli Locks for Panamax ships opened in 2016) finally San Pedro locks. Carrying on through the canal we sailed under the Bridge of the Americas to the Pacific Ocean.
Queen Mary 2. History in the making!
Captain Hall has been planning this cruise for over 4 years with the authorities as Queen Mary 2 was deemed too big to traverse the Panama Canal. It is not so much a problem since the Cocoli Canal opened in 2016 but the problem was passing under the Bridge of the Americas as the ship is too high. We had to spend a night on the Miraflores Lake waiting for the tide as there is only a short window to pass safely under the bridge. Many of us were standing on the top deck to watch us pass under it & we lived to see another day!
Usually it takes 12 hours to sail through the Panama Canal but as we had to wait for the tide on the Pacific side to be able to pass under the Bridge of The Americas it took us 2 days to pass through from the Caribbean Sea on the Atlantic side to the Pacific Ocean.

Very interesting. Thank you for telling us about your trip through the Panama Canal.

It was fascinating seeing how they operated the new locks. I have been through the older locks twice but the gates are huge & weigh approximately 662 tons.

@garymarsh6 Did you offer to help them lift them by hand? 
I've never been there so have no idea how they work.

@DaddyEvil Haha I guess they are operated by just pushing a button or fllicking a switch. The hydraulics to move them must be huge.

Wow, I love how you explained what my teachers never could about the panama canal, of course back in the 1960s teachers only touched on many of the history subjects rather than actually teaching us anything of value.
I don't think I would have wanted to go on that cruse, it seems to me too dangerous all things considered.
I can't wait to read the rest of your cruise story.

Oh wow, I forgot there are 2 kinds of cruises @garymarsh6 I think I'd rather be on an ocean liner rather than a cruise ship.

No it really was not dangerous. The ship is very safe probably one of the safest ships in the world as it was built specifically to cope with the rough Atlantic so even in stormy weather the ships design helps it sail without much rocking. It is the only Ocean liner left in the world & nothing like a cruise ship so it is very safe.

I wondered how long that canal was, it is quite a long one.
We passed through the locks at Sault Ste. Marie, and found it incredibly interesting.
Your passage took much longer as your ship was much larger and the canal much longer.
It must have been a very interesting point of the cruise.

Yes it is 51 miles long but it takes between 2-3 hours to get through each of the three sets of locks. I found it very interesting each time we have been through it,

Sorry I should have explained. That is one of the new Locks in the Cocoli Locks. It is open for us to enter the lock. Once we were in it slid out from the side behind us. They then started to fill the lock in front of us from the reservoirs at the side. Once it was level the gate in front slid across & we proceeded to the next gate ahead. The water was drained out into the reservoir which brought us down another level. Once we were let out we proceeded to the next & final set of locks which lowered us to sea level.

@garymarsh6 Thanks! That makes sense now. It must use a huge volume of water. I remember quite recently it was closed because the water levels were too low.

I’ve transited the Panama Canal. It’s an engineering marvel

It really is amazing. I also like the Suez Canal both completely different but each unique.
