See if you can get a copy of the Sailing instructions, Yachting World or Yacths and Yachting usually publich them. These will give you the codes for the bouys and courses and start times. Listen on Ch 28 for the race instructions and count down for each class. If you want to watch the racing, stick to the bigger boats or One Design classes, they are more exciting.
Keep a VERY good lookout, racing yachts are likely to tack or jybe very quickly without notice and for reasons that will not be obvious to a spectator. Also stay clear of the start/finish line (RYS, where the canons are, to S Brambles & W Brambles bouys)
The windward mark (as far up wind as the course takes them) is usually the place for the best/closest action. Stay clear up wind of the bouy.
In a F5+ some of the bigger boats will be going faster than you can, so keep looking behind.
Take a camera.
