You might haved a look at the anchor roller fitting. I replaced one of the coach bolts with an eyebolt an my B37 (2002) and from that I fly a multi purpose genoa – this has a kevlar luff rope and seems to work rather well. The limiting wind speed is about 15 knots upwind but it is a lot bigger than the standard genoa. I can fly the standard genoe & the MPG for downwind sailing.
