Eventually found all the requisite bits and got down and rigged and on the water by 11.00. Once I going it looked like I could squeak past Williamstown on a single tack, so that's what I aimed for. Sort of going wither the wind listeth. In fact I had to throw a couple of tacks thanks to the wind shifting and me being less than attentive at keeping the boat pointing as high as possible. But we get past the time ball tower, and turned into the boat channel to head into the sheltered harbour just in time to meet the Spirit of Hamburg, a substantial container ship, heading out. We chose the path of discretion, and kept close to the docks near the point. The wake from a container ship at reasonable close quarters is indeed quite exciting in a Mirror I discovered.
I turned round just off the jetties of the yacht clubs, and tacked my way back past the point where the football stadium is, then eased off into a rollicking good broad reach home. A grand day out, a bit more lively than I had anticipated from the wind forecast, but excellent fun.
