You’re teaching Yoga on a SUP and most insurance companies don’t like that. They can’t handle a drowning claim. They are used to insuring candy shops and ice cream stores. Main Street Insurers have no guts. So you’re out searching the web. People do fall off:

We do it, and it is cheap, loss cost liability, and sometimes we can do the professional liability as well.

So if your in the need for some Yoga and SUP instructors insurance both professional and general liability, is the right place to start.
