As an academic, I'm always much better at the science and the engineering than the policy. I think that's more in your purview.
From what I've seen, I think the general understanding is that boat wake can impact shorelines, both in terms of bank erosion and impact on species. For example, Professor Vermaire has been looking at the impact on nests of shoreline birds. If there were a policy that tried to minimize those impacts, I certainly would support it.
