Sorry Capt,

I can't believe that no one knows about a cunningham.

It increases the wind range of the sail without a sail change! By
pulling on the cunningham the baggyness of the main is reduced creating
a more windward sail with out a sail change.

On a cruiser, as I have done, it increases the useful life of the main
by years,

I've sailed with the cunningham set for the last three years. That is
why I've ordered a new Main.

A cunninham gives a flatter sail without changing the outhaul or the
halyard
