Not sure if this is an AUSSIE trick, but Greg (and many of the A-Class or ex A-Class Sailors) prefers to sail with Centre Sheeting, and with no cleat on the main...

But I think Greg has acknowledged that the Viper being sailed Uni needs a cleat!! (Either that or he would have to acknowledge that AGE might be an issue!!)

This was his email message to me after Day 2:
"Well it was a hard day office sailing single handed. Dominique was still very sick this morning - no way she could sail so I decided at the last minute to take the jib off and sail one up. Glad it was not windy as I don't have a cleat on the main sheet and I was running out of hands. My results were pretty poor but I beat all the other cat boats in the last race."
