Light Weather
It's not unusual for Team Racing to be conducted in very light weather (as was the case last Saturday).
In these conditions the skill differences can result in massive differences in positions, skilled teams will overtake the race infront, poor sailors can be left battleing up the first beat while everyone else has finished. It can be painful to watch.
I'm sure that one of the problems is that teams do not go out and practise when the water is mirror flat, but it can pay dividends. The other thing that stands out is the way the less skilled sailors will try and force their opinion onto the wind/boat. They will hold a sail out to catch the wind even if it is backing (or filling with wind on the wrong side). The boat will be heeled into the wind, gravity will hold the boom out, but the sail will be filled, or shaped on the wrong side. The boat can be moving backwards and nothing will change!
So what are the secrets? No 1 is you have to accept that in these conditions the draft (a very light wind) can come from any diretion. The sails will move to the slightest draft, so you have to concentrate on them and set them for that wind at that moment. Success is when the algae in the water begins to move in the desired direction. If you produce a ripple - then you are really motoring!
It's not easy - but it isn't rocket science.
