I have an 04 Centurion Lightning that I surf behind a lot. To build a good wake I have to list the boat to the side very hard, I estimate about 20 degrees. The list is so hard that we often fall off the swim deck, people often motor up and ask if we need help, motorists passing by on bridges have called 911 for us on several occasions and we’ve had the local police helicopter hover overhead to see if we were in need of assistance.
To get a face of the Vee on my Lightning to go on plane with the horizon the Lightning must be at about 20 degrees, see the picture. My best wake develops when the rub rail is very deep in the water and the Centurion lettering is in the water.
I think many other inboards are much more flat at the stern. I’m not sure where I’m going with this observation but it’s kind of interesting.
