good point, they do get bored in anything approaching safe sailing but my daughter and i start to worry when the wind picks up and it gets interesting
on my dingy i could quickly turn around to pick up a man overboard or even just dive out for them and the boat would round up quickly
but on the nacra it'd take me much more space to stop and come back and if i dived off the cat while it would round up eventually it would be too far away to tow a child
