Main thing is the little fella looks happy.
Robby Swift started windsurfing when he was 3 years old and his dad made a promo video of him sailing when he was 5 - if anyone can find it?
Great stuff! Wish I'd learnt at that age.. Mind you I suppose windsurfers hadn't been invented when I was that old..
