Hi Scarecrow,

Interesting and good to know. Would that also be the case for a pocket sleave luff system over a round section extrusion? This is definitely a concept I was impressed with when I was originally reading about the F12 Vudu. Looks modern, simple, light (I assume) and I guess is cost effective and fast I guess, as seen on moths, sail boards, etc. Is it considered a cheap option? How would you lower the sail while on the water?

Regards,

Ross
