Adults can also fit into and sail optis and sabots, but that doesn't make it a good idea.
When the tornado was dropped from the Olympics one of the major discussion topics was development of a pathway into performance catamaran sailing starting with the kids. While there are a number of small cat classes around (arrows, arafuras, paper tigers), few were deemed suitable for kids only as a development class; too heavy, too much sail area, too complicated, too many adults already sailing them, too ugly.
The F12 can fit this niche very well, if the market desires.
Your spot on ncik
The F12 gathered so much momentum because it filled a gap in good promoted childrens catamaran. There are no end of small cats out there an adult can carry and rig. This is one of the very few that a 10 year old can rig and manoeuver to the water. If an adult came to my club looking for a relatively light, easy, safe cat to learn on I would recommend a Mozzie, F14 or an Arrow depending on their weight.
