Bear HELLO welcome to the 21st century.
THey are the specs for the Mk3 !!!
AND while you've been dreaming, we've gone metric !
Also that is for a wire luff not for a furler which may be adjusted.
Mark, putting a deep reef into a sail is not good for the material. The material in a storm main or trisail is much heavier to withstand the load. That is why most sails only have 2 reefs.
Your splitting hairs Bair. (MK3 measurements in Brackets)
Luff 15' 6" (16' 6")
Foot 7' 11" (8")
Leech 10' 3" (11" 6")
That is why Mk 1s look pretty sitting on moorings and Mk3s are the fastest.
Remember that boat we saw a couple of weeks ago at Croudace Bay with reef points 500mm apart right to the top of the mast.
Greg, ps I'm always right.
