Hi Sharkbiscuit,
This idea is all about taking baby steps towards having our own race in the style of the Ledge to Lancelin race (
http://www.oceanclassic.com.au/ ).
In fact, there used to be a semi-regular Wednesday night race (weather permitting) from Seacliff to Henley Beach (in front of Dave Marsh's shop, and yes Russell he did have beautiful teeth

).
I think the record was held by either Lindsay Newbold or Mike Sagan in around 18 min or so. Still an impressive number.
This style of racing is off the wind, and works along the metro coast in a seabreeze. Think of sailing about 130-150 degrees off the wind. To do that, you need a bigger sail than used for beam reaching, and probably a bigger than normal board for security. The gear to you use isn't crucial, but going deep off the wind is "all a bit different" if you haven't done much before.
The big sail helps in getting back upwind again if you haven't arranged a pick up.
I've added a photo of the course - no need to go more than maybe 800m offshore.
Nothing is compulsory and only take on what you are comfortable with of course. I'm no expert that's for sure. Just trying to add another dimension to our summer sailing and maybe one day we can see some SA sailors doing well in the next Ledge to Lancelin.
