I looked at the .org site, and I could only find a section in the FAQ which stated that I *could* add a window, and what size it could be for racing (like i'll ever race!), but did n't find anything that explained how to delicately slice and dice the sail and add the window. I desparately need one as crouching low and peeking under the boom for hours gets quite tiresome. Anyone out there done this, and could offer a "how to"?
