Now that I look at the picture of #705 a bit closer, it appears he has a little bit of down-haul tension on, (note the lack of luff wrinkles and camber in the sail, at rest) which makes the foot look closer to the boom than it would be without tension.

My Glaser main is a good 6-8" above the gooseneck with no tension on, but I can easily pull it down to the boom with some downhaul. So to re-cap. Robi's Ulman was about 6" taller and a little narower, my Glaser was a little shorter but fatter at mid leach. Kind of like it's owner... <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />
