Been sailing my Mach One 6.2 for over a season, and love it but always struggled to get the cams to rotate. Kills gybe exits every time. Rigged on recommended Severne 430 at about 2 cm under spec downhaul (at full spec the leech seems too flappy). I'm pretty much on spec for outhaul depending on conditions.

On a gybe exit I have to give an almighty snap to pop them around. Only really works when there's heaps of wind, and is very tiring late session. If that doesn't work, I try to really get it loaded downwind to pop, but most often end up pushing it by hand.

I've taken out all spacers, and tried more/less outhaul/downhaul but can't crack it. I'd prefer a fuller belly, but the cam issue makes me down/out haul harder than I want. I'm resigning myself that it's just how race sails can be, but eager to hear if anyone else out there has similar experiences or advice for me.
