I applaud what you’re trying to do and I hope your efforts will lead to some much needed new regulations and better enforcement. There’s a real problem with boat and jet ski rentals and making sure the the renters know what they’re doing.
I’ve seen a rental company delivering jet skis at our marina several times and they don’t appear to provide any instruction about the rules of the road. I’ve also seen some crazy behaviour as soon as they leave the launching ramp.
I look forward to hearing more about your work.
