Your logic makes absolutely no sense. Do Optis turn kids off of sailing monohulls? We're talking about a training boat for a solo 13-year old, here. When he gets good on the Wave, and finds a good crew, then move him up to something faster. Don't jump right to the fast boat and scare him off sailing when he gets in trouble (as others have mentioned).

Waves are fun for adults too, as others here will attest. Faster than monohulls too.
