I took the hull measurements and overweight of the Texel website. I'm sure about the hull measurements and I don't trust the PC weight quotes.

I've estimated the luff lengths of the various sail on the size of the sails and what is specified on the Texel website for a normal rig. I'm confident that I'm close enough.

No spi as requested.

Weight 185
rated length 5,79
Main area 17,67
Main luff 8,7
Jib are 6,98
jib projection on mast 5,9
Boards yes
no spi
doublehanded.

TR = 100 (no spi) and 96 with texel style spi od no more than 21 sq.mtr.

With weight 175 the ratings drop to TR = 99 (no spi) and TR = 95 with spi.

I hope this helps

Wouter
