Hey Ginno.
I think the right gear and gentle persuasion and the right venue. And +++No Stress
My son who has just turned 8 has been coming out with me on my inflatable SUP for a long while now. Both paddling and sailing. It also makes an awesome play platform for him and his mates, just need to wash the mud off afterwards.
Tried him on the SUP with this rig at Easter and although it was nice and stable the small sail had no effect on the board and he was not able to steer.
I have since picked up a 2nd hand 122 Kode, with centre fin slot and full EVA deck. He had his first sail on it this September Holidays at Elanda Point.
First day we tried was a little too breezy and had a little chop. So it was a bit of a challenge, but he enjoyed his couple of stacks.
Second day was really light, but by the end of a short hour session with the bigger 1.5m he was able to sail away from me, drop the sail and turn the board, uphaul and sail back to me, steering as he went.
Both of us were very chuffed with that.
Added a bit of tech as he got to wear my GW60, which was popular too.
As a Bonus the Kode is a good size for me when the wind comes in, so I am not bringing an extra board.
Looking forward to another session soon.
