I didn't really mean a full out donation, no manufacturer could afford that, but more of a "Lease", and then have an entry fee for each country/team which would go to pay for the boats. Then after the regatta the organizers could sell the boats and either pay the supplier or use the money to invest in the next fleet, 4 years later.

I think a $20,000 entry fee, per team, would still be a lot cheaper than what the teams would pay to first buy and then ship their own boat to the Olympics.
