While PWC have a higher profile than paddleboards and kayaks, it is like being on a motorcycle in traffic.
I live on a lake and have a PWC. I only take it out on off/weekdays, almost never on weekends.
Here We have rentals that tourists rent by the hour. Every year, one or more get killed because they do not know the rules, or they can’t handle them properly. Have had a few run into things like docks and bridges because they can’t stop in time..................
