Hi Wouter

Allot of text ;-)

as you said:
-1- First is trivial, If both are sailing without a spi then the sloop is definately faster around the course.

i was thinking that you were talking of a restricted sail area, the same area for the uni and the sloop.

Now if we increase the sail area for a sloop, to the max a plattform can carry for a given windspeed, i agree that the sloop (with the same sail area) will be faster and the uni is in trouble, but as soon that there is less wind, this advantage will be lost to the uni and the uni is faster.
