Hi Simon
I thought I was going mad but I knew I had read this somewhere:
Other main rules
* Mid height width of gennaker is at minimum 75 % of length foot.
* Boat must be rightable by any crew either solo or doublehanded
* The rig may not be trimmed between start and finish by other means than sheet, downhaul, outhaul, traveller, mast rotation and halyards systems.
* Only "soft" sails are allowed.
* Using multiple sets of the top three battens to fine tune the rig to the crew (1-up/2-up) is permitted and does not require remeasurement of the sail
* No ballast other than corrector weights are allowed
* The wearing of bouyancy aids is compulsary during (open) Formula 16 races

Therefore it seems as if we have a contradiction in our rules? <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />


With my UK measurer hat on I would say that we are using a "sheet" to change the diamond tension.

The general definition of a "sheet" is "a length of rope used to alter the angle of the sail to the wind".


Which in the broadest sense it is doing as mast bend effects sail shape and that effects the angle of the sail to the wind.

If asked to rule on this, I would allow an adjustable diamond setup that was adjustable while sailing.
