After talking a lot about turbulent wakes this week, here are two pictures of different kinds of wakes. They are of course turbulent, too, but on a very different scale.

In the picture above, see how you see pairs of eddies on either side of the row boat’s wake? That’s where the oars were in the water! But this wake stays visible only for seconds, maybe a minute. Nothing you would be able to see for a long time from afar!

Same for the waves the birds made. Can you still spot that they were swimming in the same direction as the row boat and then made a 180° turn? Maybe you can, maybe you can’t, but that’s how quickly those wakes vanish.

Now below: This is a very interesting wake. Since the SUP board is pretty much flat on the water and doesn’t displace a lot of water while moving through the water, it pretty much only creates the V-shaped wake, not a turbulent one the way a ship does when it’s displacing a large volume of water in order to get forward.

Think I’ve said everything there is to say about waves? Well, then just enjoy this one from the ColorLine ferry that sailed past a couple of minutes ago… How beautiful is this? :-)
