Back to that boating thing for a second. Both I and my wife grew up around boats. I grew up around airplanes as well,my wife did not.
Most children take to watercraft quite willingly, so there's no reason not to start them young.
At first, all they can do is ride in the boat.
After a few years, they're ready to ride on an inflatable. I will warn you that they will want to stay our all day, but they can't do that, they'll get both sunburn and abrasions from the tube.
Somewhere around age 7, you can start them with a kneeboard.
They're also still interested in riding in inflatables, but want a wilder ride.
Moms can occasionally be persuaded to get on an inflatable as well. First rule of giving moms a ride is keep the inflatable within the wake, no wild teenager rides for them.
Eventually, it's time to try wakeboarding or wakesurfing.
It's challenging at first,
But very satisfying once they get it.
And, everyone learns to drive the boat.
