Oh no you Dint!
If we are going down that road, then I think the Single Handed boat should be a spin boat as well!
Go UNI Racers!
I am not on the committe... BUT... this is a bottom up process.... This is about motivating a class... find a club, partner with US sailing and have the US chamionship.
If the single handed spin class can get organized, talk with the committee about what they are looking for (standards), make a proposal, partner with a club and make it happen... so YES a single handed spin championship could serve as the alter cup championship.
