Phill and others,
The idea behind a 14ft version would be not only quick and easy but cheap. I may even end up building a 14ft for myself.
Over the last months, while playing about with landyachts, I again renewed my desire for a simple small catamaran with a unstayed rig. Just a single sail craft that is easily fully assembled and disassmebled. I'm convinced that a market is to be found for such a craft if its hulls look pleasing enough. Both for kids and adults alike. I too would love to own such a craft fro the small spare hours that I'll be getting in the next years. Not having complex systems like a spi or trap are actually benefits in this concept.
Anyway, take this thought as a general reply not as say advice or anything.
Best of luck !
