Yeh, I did a bit. I wondered about a wake being different but just went ahead anyway. However, the phenomenon Biggles is describing also occurs on the backs of ocean waves especially if they have bottomed out. It can be difficult, or impossible, to climb up the back and over some waves.

I don't understand your explanation of the airation and turbulance in the wave and the snowballs.
- its all a giggle - who wants to come and see a ship test tank with dye colouring to learn about the structure of wake & waves then?
I'd love to.

As JW says I have noticed this on both large waves and large wakes.

you will notice it on the leeward side of any wave - but if its wake - your ability to power out of it will be greatly reduced.

Natural waves have much more powerful rotation from the trough to 40% of the wave height - if you could stick razor blades on the vortices - you would not end up with a fragment bigger than a ten pence piece - based on a 6 mtr boat -
