The N15 size is right for solo rider too as seen above, so it can serve for a youth crew, Dad & sons or a solo ride, same as the Formula F16 platform allows. The Viper F16 now offers a foiling package too.
Lets see how the Nacra 15 Foiling version will develop for the youths, but I think its a good decision, safety will need to be addressed and the L rudders are a good choice in that aspect.
