Here's some follow up on the Wake Experiment #4 with what I'm calling the Surf Switch.
Here is a set of photographs comparing my regular-port wake against the Surf Switch enhanced wake. Note the Surf Switch wake was losing ballast during this test. Regular Baseline photos are marked in the upper-left hand corner with RB and Surf Switch photos are marked with C8 in the upper left hand corner. The speed in mph is marked in the upper right-hand corner. Note that Perfect pass is under reporting speed by 10% to 20%, i.e. speed is faster than marked.

For speeds above 9 mph the face of the wake is cleaner – less white foam.
For speeds 9 mph through 11 mph on the RB photos you can see a middle wake feature made by the hull extension that makes the wake curl early.
For speeds at 9 mph to 11 mph the formation of foam at the end of the wake starts further back on C8 than RB.
For speed for 12 mph and above the formation of the foam at the tail of the wake starts about at the same place but the shape is different.
For speeds 10 mph and 11 mph the RB rooster tail is large and vertical.
I can see there’s a difference in wake shape, but more work needs to be done to “dial in” a Surf Switch wake. The rooster tail formation needs to be looked at as well.
