Some details - there is a full set of rules, with the main stuff of interest copied below - the full rules and details will be discussed at the briefing (re transitions, scoring etc) and can be email prior if requested (PM me with a email address)

BBQ available at “lunch time” for use by competitors - $2 for steak sanga.

Teams can be comprised of 2 to 8 members .
The primary aim is to complete as many laps as possible between 10:00am and 4:00pm. (and have a bit of fun!)
Each participant is required to be a financial member of a WNSW affliated club (due to insurance requirements). The competitor is required to lodge a registration form and a liability waiver form, prior to entering the water and sailing the course. Sailors who are not members of a club can join the IYC Windsurfers for $25 on the day.
All competitors are required to wear a suitable for purpose Type 1 or Type 2 PFD while sailing,
The course will be set in the areas in front of the IYC based on the wind and water conditions on the day. A lap may take anything from 8 minutes to 20 minutes, depending upon conditions.

it will have to be tailored to the conditions at the time - but definately have a upwind component in it - upwind/downwind or triangle are definate options

the intent, wind conditions allowing, is to have the course in the bay in front of the club which is pretty well weed free (touch wood)

the main body of the lake itself is not good for weed at the moment - rapidly deteriotated over the past few weeks - if we are forced out there a weed fin would be useful for the longboards (we raced formula boards ok last weekend out there so its still sailable without one)

if you haven't been ingested into a team prior, we'll find a place for you on the day no problems
