I use the recommended mast, Severne Blue Line 540. The sail is rigged with the recommending settings. Almost every time I flip the sail tacking or jibing, the top 2 cams pop off the mast. Sometimes when the sail fall in the water the same cams pop off the mast.
Mim said that I need more outhaul, but I feel the sail is OK with the outhaul I'm using right now, if I add more outhaul the sail loose power.
Maybe I'll need to put more spacers, but I don't know how much and the sizes.
