John, simply find a clamp that goes onto
one inch or 7/8 inch tubing, one with a clip at the end, and run your lifeline to that. Buy or make one, lotsa clamps out there. Or simply weld a small ring - go look at the pulpits in your marina.Our C25 had that sloping lifeline, too. I agree it was dangerous to go forward with that arrangement. What you do is put a pendant on the tack of the jib and raise the foot higher to over the bow pulpit, or get a furling system with a higher drum. Then the bottom of the sail is above the pulpit and lifeline and you can run the lifeline straight.If you're a die hard racer, you'd want the foot of the sail as close to the deck as possible.Can't have it both ways. Your boat, your choice.
