Andreas, If you think there's a market for a 'junior' catamaran, why don't you go ahead and build one and clean up but I'll save you the heartache.
The problem with building boats (cats) for juniors is that nobody buys them. There have been any number of good 14ft and smaller boats built specifically for the younger cat sailor and the builders generally sold NONE! Not one or two or a couple of hundred, NONE! Bill N. from Wangie on Lake Macquarie did a lovely little cat he called 'The Glider', very much suited to the juniors. He made six I think and still owns them all. Jim Boyer did one and sold none and I could go on. And in any event, 13.5m sq. on a 14ft boat with sufficient beam and correct rig isn't ridiculous for a junior to handle and if it is then 14ft isn't a baby's toy then is it .

It's this 'bigger must be better' male mentality which marketers promote to sell us their bigger (more expensive) toys which keeps us poor or working our dates out trying to afford the 'right' size boat/car/house........ which always happens to be the next size up to the one you already have.
The guy on the boat in the attachment is a school boy competing in the combined schools regatta at Belmont NSW.
