Do your kids a favour teach them on some equipment designed for them. The board in the vid is a JP young gun and it is perfect for teaching your kids to sail. 12 yo Rachel is using a 3.5 sail with rear fin only. The location is Inverloch Vic. which I believe is the best spot to learn in Vic.
crikey Jman she's a better sailor than me - how smooth was that gybe. I've got a 11mth old at home and a kids board is definitely on the wish list for the future..
