If they were fitted with a jib of about 3.7 sq.mtr. area then they would be.

Why don't you spend some time actually familiarizing yourself with the Texel rating system before shooting off in all directions.

And after that ponder some more on my statement :"... it was modified to be an F16. The rating difference, however, is caused by the fact that it is sailed doublehanded without a jib. Texel rating system then predicts an 11 % performance loss. ..."

I'll give you a hint : "11 % performance loss with respect to the same design when fitted WITH a jib"

Before we create anymore confusion. That Bim 16 will sail off of a rating 102 in Formula 16 class races; ergo first in wins whether or not it has a jib or not.
