How likely are you to flip on the kayaks?

Of course varies by water, surf conditions and if you want to move on the kayak, but having done a dozen outings, barely get wet let alone fall or flip

We had a group of about 15 kayaks. There was 1 flip but it wasn't a big deal. They did not know how to swim bit the life vests were sufficient and the instructors were on it.

I did not see anyone flip both times I went.
