Sure - but who's footing the bill for the gas and salary for the five or six power boats following each of the teams equiped with wireless equipment 6 to 16 hours a day to try and capture the 5 seconds of excitement that may or may not happen? Who's driving the boats and who's training them to stay out of the way of the sailors? Most of the good stuff would be lost anyway because unless it's a huge power boat, they're not going to go out in half the stuff we enjoy anyway! The odds are not good on capturing the excitement offshore.
However, you bring up a good point through the surf. That would be easier to capture wirelessly since everyone is congregated. With just the before launch, launch, and arrival I'm sure there's enough good stuff happening for 20 to 30 minutes of TV worthy stuff per leg. Don't get me wrong - I'm all for getting some on TV coverage for a race like the Worrell or Tybee.
