My brother had one for a couple of years. Around here, as long as you avoid the busy beaches there isn't nearly as much danger in running into another person on the water. Not saying it's impossible, but it's a big ocean. I can see how sharing with water skiers in a lake or river would get tricky though.
I did have a near collision with a curious pilot whale last weekend though. A younger one broke away from a pod I was watching from my sea kayak and came over to watch me instead. Very cool experience. I'm not accustomed to close encounters with them.
