So maybe we should just forget about what the youth boat is going to be and figure out a way for our youth sailors to get more experience on cats with spinnakers, no matter what brand or size of boat, since it is obvious that whichever boat is used for the Worlds, a spinnaker is going to be used.
OR, we can at least get our kids into monohull spinnaker classes to get them the spinnaker experience, until we have enough youth spinnaker cats in this country.
Have your kids race spinnaker boats like the F18 (or even F16/I-20) of dad, uncle, friend, etc . And do so as much as they can. There is honestly not much point in having them race plain sloops. Spinnaker sailing is just too different. Even monohull spinnaker sailing will be a bit far fetched. Only 49-er, 29-er mono's comes relatively close as they too have asymmetrical spinnakers. Forget about 420's and 470's.
And then when they have won the US slot for ISAF youth championship then have then do a crash course on the US sailing SL16. (That is when US sailing has bought a SL16 for that purpose)
