Thank you for mentioning the Aqua Cat. It's too bad that boats that already exist and that would be great for kids and that are inexpensive are ignored by the sailing community.

When they were very young, Randy Smyth and his brother sailed an Aqua Cat (the next size larger, I think) in a race to Catalina Island and back.

Unfortunately, the Aqua Cat does not get any publicity because, for some reason, the designer/builder has chosen to separate himself from the multihull world and not try to market to multihull sailors. (I was told that when I tried to get them to advertise in "Catamaran Sailor.")
