Interesting, thanks for sharing. Something strange I noticed, it seems they are not meeting any other ships going the other way? Is there separate locations where boats are waiting before they continue?

Second note is that it's easy to notice how windy it is and how easy it would be to get stuck in the side if you're not paying 100% attention. At many points in the video you can see the ship it's filmed from pointing in one way, but actually travel a different way.
