The Dragoon is the RYA Junior training cat, The HOBIE 16 is the RYA and ISAF youth training cat. It would be the Hobie 16 that could possibly make way for the SL16 after 2007. But, without opening too much of a can of worms, the fact that there were 70 odd Hobie 16s at the recent youth europeans, may mean that the status quo may remain a bit longer.
As a parent/owner and sometime trainer in both the dragoon and 16 classes, i can thoroughly recomend them both for their junior/youth roles.
