He would love that!!! For now he can have fun in MY boat!!
By the way, he sails the big boat better than many adults I have seen. Sometimes, after school I go sailing with him, I do sails and trim and he does the steering. He can really really do it, like a grown up, tells me when to tack, if the rudder is "bitting", and one day actually told my wife that he wasn't sure I knew what I was doing (we all laughed).
I bet he would love the Catalina.
