As far as I know the rules are as of 2019.

I’m convinced they were changed to accommodate the taxi cooperatives and transport companies, and with the pandemic they have probably had other things on their mind.

I no longer do the kayaking tours. The company Venice Kayak is still there, but it is run by others now. If there’s been any changes, they’ll know for sure.

In any case, enjoy your paddling and I do hope you won’t have problems.
