Longest Straight Line Sea Voyage Route on Earth!
 
Howdy folks!

I came across this interesting animated graphic today that shows the longest possible straight line ocean voyage on Earth that does not touch land at any point.

It is 22,000 miles or 35,400km. Remember, that is a straight line, without touching land at any point.

While it is a route that no one would likely sail simply because of prevailing winds. It is interesting to see the route and if you watch for a moment, the animated globe will turn. It may take a few seconds to load the Google earth animated graphic.

No way. The earth is curved. There are no straight lines.

You're gonna hit icebergs at at least one of those polar extremes... Technically not land, but I'm betting the effects are the same.

Stick around for a few years..the ice will all be gone :biggrin:

Can't be bothered to check which one is correct, 'cos I'm sure not going to be doing either one :) , but here's another source which says Pakistan to Kamchatka is the longest. (see Map 38)

Straight line or big circle route? Obviously from the tip of southern Australia you need to hang left to get to northern US.

I love geography, so when I see a chart or map, I am drawn to it. :)

My Pet Peeve: Mercator Projection wall maps mislead people into thinking continents are a certain size, because of the distortions caused by the projection. I have large wall maps in my study, one in front of me and directly behind my computer. I enjoy looking at it, but always remember it is a distorted view of the world. :D

I often point out this difference (distortion) to children when I see they have a globe, as I want them to see that the real relative size of the continents (shown on the globe) is much different than what is shown on a typical wall map in their room or in their books. The visible difference can be astonishing. :)

For example, Greenland looks HUGE on a Mercator map, but is much smaller on a globe.

Similarly, Africa looks big on a Mercator map, but not as large as it really is (on a globe).

Simply put, as one looks at the Mercator maps, the further from the equator (closer to poles) one gets, the more distortion there is shown, with the land masses being stretched (enlarged) as you get closer to the poles.
____________
Clip from an article: "Created by Flemish cartographer Gerardus Mercator in 1569, the Mercator projection preserves direction, instead of size, making it useful for navigation."
_____________

Here are a few illustrations to show the relative size of Africa to other countries and to Greenland. These illustrations are based on actual surface area comparisons.

Notice that Africa is about twice as large as the former Soviet Union!

Notice that the Continental USA and Europe and China AND India could ALL fit inside of Africa! That is HUGE!

Notice that Greenland is actually MUCH smaller than Africa, only about 1/14th the size of Africa, now go look at a typical Mercator map where Greenland appears about the same size as Africa, because of Mercator distortion. The second illustration shows a blue Greenland overlaid on top of a pink Africa, in both Mercator and actual size.

I am also including one projection map (see the map with the blue water) that says it shows the true size of the land based on actual surface area, so it may look a bit distorted or odd, as our minds are accustomed to the Mercator projection maps.

If my sons are steering there are no straight lines.

When i tried this with string on my library globe, it did not work, at least as a straight , unbending line. Really got three great circle routes combined.

I also have always enjoyed maps, I'll do some more looking into this, I've seen this longest straight sail a couple times before, there have been ones with keeping the same compass heading, and then great circle routes. Also I was just told that Marvin Creamer just celebrated 100 years old, he was the first sailor to circumnavigate, at least in recent history, without any instruments. He did it to prove that it could be done and that man could sail the oceans before and without the aid of a compass and clock. His book is an extremely good read. I just got an email, they just put up a monument to him in south New Jersey.
