Would you fund it out of your pocket? $2k for the sail, freight, repairs, time to administer it, liability insurance and provision for theft/replacement due to wear. All that has to be covered by $25/week.
To make it viable you would have to charge $100/day the sail isn't at home base, minimum 2 day hire, customer pays the freight.

If you believe the idea is such a winner back it yourself, the class has a track record of adopting ideas which just make sense. The spinnaker was funded and developed this way by Tim Sheppard, others where involved I believe but he made it happen.
Good Luck,
