As a licensed captain, I might have another take on this. I am concerned with safety and rules of the road. Most new boaters don't have a freakin' clue about rules of the road. I was once running a charter boat and was almost run into a rock jetty by a Harbor Police boat that turned the wrong way in a head-on meeting situation. I had to slam the boat into reverse and hammer the throttles to keep from hitting both the Harbor Police boat and the rocks. Another time, I was running a commercial boat on Lake Powell and was half-swamped by a power boat that ran full speed between me and another houseboat. I turned into the heavy wake and got half the boat full of water. The other boat got "waked" badly and I'm sure broke a few items on board. Simple rules of boating that boaters NEED to know.
