Here is a link to the FAQs of the 2022 study in layman's terms:

Some quotes:
The report indicates the following outcomes:
1. Wake waves produced by wakesurf boats during wakesurfing are measurably larger than non-wakesurf boats in terms of maximum wave height, total wave energy and maximum power.
2. How a boat is used, or its “typical operation,” is an important consideration. Non-wakesurf boats can generate large waves when they plow water during acceleration to or deceleration from planing, but these boats generally spend little time in this condition. Wakesurf boats used for wakesurfing generally spend a majority of time in this condition. Non-wakesurf boats can be outfitted with aftermarket devices, like a wake shaper, to create wake waves suitable for wakesurfing.
3. Data like those produced in this report can be used to inform guidance on operational distance. For example, this study infers, depending on which non-wakesurf boat reference condition is selected, that at 200 feet of operational distance, the wakesurf boats would need to operate at distances greater than 500 feet or 425 feet from shore/structure/object, etc.
4. This study was limited to four boats and the testing period was relatively short. The study’s data and findings are important additions to the growing body of research in the area of wake waves; however, more studies of this type, as well as studies focusing on how waves and propeller wash interact with lake bottoms, shorelines and structures, are needed.
● Did this study examine shoreline erosion or failure of shoreline protection resulting from large boat waves?
No. The study did not investigate these topics; rather, it focused on characterizing the wake waves themselves. The results of this study will support further research focusing on environmental impacts like shorelines.
----------------------------------------------
Has there been any further studies done? It seems ludacris to draft broad legislation based on this study consisting of testing the wakes of
4 boats (2 wakesurfs/2 recreational boats) all 25 ft or less in a
2 month period.
