Ah, the picture does not show it, but there is a traveller. The old fashioned "set-the-stops" variety.
Windward performance is ok, not stellar, in ideal conditions I can usually
pinch to about 35 degrees apparent
but that is with new sails
and a freshly cleaned bottom on smooth water
. 45 degrees would be more usual and that's not exactly efficient in VMG, better around 55.
It's interesting, but I have never felt the sail shape was a problem, at least not with the new sails
, so I am never finding myself feeling the need to really crank down on the main sheet. The boom does extend a fair way past the clew so maybe that is giving me the added leverage I need, that and the lower aspect ratio.
Still... 12:1!? Gosh.
