Mate of mine cruised for a couple of years with his family aboard. Six-year-old son (when they set out) was mad keen on fishing, Dad didn't like fishing mess on the deck. No conflict for the first 18 months as the boy never caught anything. Then in one anchorage some unprincipled ratbag told the boy he should have a baited hook on his line, not just a sinker. Some people are just plain irresponsible!
