When a ship has sailed past, at first you see only its wake.
And then you see reflected bow waves interfering with the original wave pattern:
I really like observing the wakes of ducks. Much easier to watch than those of ships because the scale is much more person-standing-on-the-sea-wall friendly. Also much less turbulence messing up the pattern. And you can get closer than you usually could.

Another awesome way to make my point about how waves look really differently depending on the angle one looks at them. Below for example my “other” way to observe waves: See how the wake leaves a shadow on the sea floor?
And some more ducks from a different day, because I like them :-)
This post has been in the making for a very very long time. I have now decided to stop overthinking and just share the movie with you, because who wouldn’t want to watch the wake of a high speed catamaran? This is from my not-so-recent-anymore trip to Heligoland.
Since I am too lazy to annotate, you will have to figure out by yourself what is happening when. But I give you this: It’s speeding, then slowing down, and then speeding up again. And in any case, it’s mesmerising to watch!
Just because it’s fun! :-)
I’ve mentioned before that I tend to stare at water when nobody else seems to find anything interesting to look at. So just because I’m weird, let’s look at some more water.
For example here. What could have caused waves like those below?
Yes. These guys went past and what we see are both the circular waves caused by the oars and the stern wave of the boat.
Ok. So on to the next riddle: What could cause what we see below?
Right, that was him:
Yes! Him again!
Does anyone see where we are going with this?
And a last glimpse on the way back:
Isn’t this the most beautiful city in the whole wide world? :-)
