How many boats are we expecting to turn up for these weekends guys?

I'll be there one-up for the first weekend and then with my 12 year old son crewing for the second weekend.

The weather forecast looks reasonable but with showers. I take it that the water will be &*?@^% cold so it's a drysuit job?

I plan on arriving around 9:00am on Saturday morning - will the club be open at that time?

What's the deal with the club? Do we individually buy a day ticket on arrival to use the facilities? Or has anything been organised 'groupwise'?
