My two children started boating at about 6 mos. It's tough on my wife handling the kids while I handle the boat but we still have fun. I try to keep it under 50 MPH when the family is on board. My kids don't get scared but my wife does. Make sure you have plenty of sun screen. I have one of those "Anchor Shades" that I put up if I am going to be sitting for a while.
