But is the f12 designed for 5-10 years olds to sail solo? or is it the "next boat"?
It depends on the sail size, risk apetite and number of kids on board.
Kids in this age range can sail the F12 two up normally. They can also choose to take some risk and sail singlehanded below the ideal weight. Parents who don't like that risk would simply rig a smaller sail.
