Yes, yes, yes for more time in the start box, if possible a bigger start box.Nathan pointed out that so far Port Entry significantly advantages your start and the likelihood of winning the race. The worst case would be that the boat which, by draw, had the most Port Entries won the Cup.
I think there is too little time in the box before the start, and 5 or even 10 minutes of Mano a Mano with boats this volatile would enhance the event. I also think the artificially narrow racetrack is problematic, at once keeping the boats close together but making it very hard to pass.
I also think the races are too short. I would target races that were closer to an hour in length. The 18’s seem to be able to keep the audiences attention for that long, I expect the AC should be able to do the same.
Recognising the commercial need for max action for TV viewership, I think race lengths are about right.
The other biggie for me is a TV director who is an experienced sailor, preferably match racer, who focuses his shots, cut and edits on showing a visually logical story. Example: save shots of crowds cheering for a simple tack, or similar. Avoid beauty and sweetening shots when one boat is rounding with another in their wake. I want new viewers to come away with a better appreciation of the sport and not a recollection of jumbled out-of-context action shots.
