My incidences Genoa does not have a foam luff. It’s not a thing of beauty when furled but it’s good enough even for upwind work. You can’t point as well in increased seas anyways, even in a 55. The Leads are too far back also if you furl more than 3 marks. So If it’s blowing 25+, I use the staysail upwind. I have reefed that as well in more than 35 kn upwind. It looks fine. If I did not have a staysail, I would experiment with a foam luff. If it’s no longer working you can always replace it.
