Randy Smyth probably could have done it at that age. He was younger than that, wasn't he, when he sailed an Aqua Cat to Catalina Island in some race?
I hadn't heard about that. I'd love to know the details. I can see it now... Set adrift on an Aquacat as a baby and raised by dolphins and seahorses to come back to civilization, open a sail loft, and dominate US multihull sailing. That would go a long ways in explaining his prowess.
