my 2 cents...
Capt. Jon,
Considered installing netting when our daughter was born. Then opted for the long term benefits of teaching her "safe" boat manners.
At all time (at dock, at anchor etc.) in cockpit and deck a PFD had to be worn, when on deck under way a harness was added. Never went forward while underway without adult supervision.
When she was a toddler I had her car seat "anchored" in the cockpit (also had a secondary anchoring system down below for tougher weather and sailing conditions), when carrying out manoeuvers she was instructed to buckle up in car seat. It worked great. Would also sleep several hours in her seat while we sailed.
She has seen me wear a PDF on a constant basis whenever we left the dock (Still to this day I never leave the dock without one). I know I did not need to wear one all the time but it was the sacrifice I made to ensure that she could never argue with me about wearing hers.
Now she is 14 years old, she is like a ballarina on the boat, still wears her PDF and ensure that any of her guess will do the same. I often hear her tell her guess..."one hand for you and one for the boat", I guess hearing so often from me, really made it sink in.
Good habits die hard.
