I sail a stingray at Kingston SE South Australia in a cat and windsurfer club with my four kids. They showed an interest in sailing so I bought them a 420 which gives them ownership and commitment but after the adrenalin of a screaming reach on the cat and rescue boat proving that breakages are manageable its a battle to get the 420 in the water. The downside is the kids need your attention so I start at 8am race day and by the time the race starts Im buggered with waterlogged hulls, but at least they all get their turn.I have no shortage of crew my problem is I cant use them in scary weather so I am looking at self tacking jib setups to solo in the weather that has them looking longingly at the clubroom. My best memory of 2005-2006 race season is my eight year old daughter laying flat on her back on the tramp with her feet planted on the lee hull pulling the jib on with all her might, it should be a bit tighter but I leave it there. Its winter here and they keep asking when does sailing start. So I guess my answer to your problem is finding the time to devote the attention and praise the kids need.
