To start you want to get a good drift hover. You don't want to get too much height or too little height. This is the spot I typically aim for and I jump either as soon as the splash animation plays or right after.

While hovering you don't want to hit the boat on the right and you don't want to go to far to the left. This may not be entirely accurate, but it should give you a rough idea of what path to take.

When you get to the end you want to hit the the rocks on the right and immediately after you hit them, hold left until you void out.

If you go too high you'll clip back in bounds. If you go too low the skip won't work.

If you pass the lap and it doesn't trigger the next lap then you probably went too low when voiding out. When this happens, the game thinks that you are on the previous lap so you would have to do the skip two more time to get to the next lap. Hitting any of the points that I said not to hit you'll probably see this purple triangle which means that you failed the skip.

It'll probably take a bit of practice, but I honestly believe this trick is easier and more consistent now then Winding Wetlands skip.
