Most likely. They are not supposed to trigger when getting wet, even very wet, but are supposed to trigger when you go into the water. You really shouldn’t wear an auto-inflating PFD in a situation where going into the water isn’t 100% a bad thing. Kayaking seems to be one of those activities where you wouldn’t want it. Even dinghy sailing/racing seems like a poor use case. In case anyone is unfamiliar with them, though, they all have a manual pull handle that is supposed to trigger the CO2 canister, and as a 3rd backup they even have a tube you can pull up to your face and a one-way valve so you can blow them up with your mouth.
