Here's a couple of suggestions for the next contest:
1) Madate that all crew on board be citizens of the country their boat represents. I think it's absurd to require that the boat be constructed entirely in country, but allow teams to shop the world for crew.
2) Require the defender to guarantee a purchase of at least $1,000,000.00 of television advertising across whatever networks/stations broadcast the race live nationwide. Assuming a LV Cup runoff, require each challenger to similarly buy $500,000.00 of TV advertising and the winner to kick in an additional $500,000.00. Maybe then we could get at least one channel to cover it.
