Old Geezer said:It's very easy in light air to roll tack a Sunfish so it comes out of the tack faster than it went into it. And it's also very easy to see someone doing this. And, like John Fonseca, I will protest you if I see you doing it - and I will get two witnesses to support my protest - and you will get thrown out of the race.
