Hello everyone, geat forum btw. I own a simmer scr 2019. Very nice sail with excellent built quality. I bought it with a rrd dynamic sdm pro 100% carbon content 2018 mast. The local dealer from who i bought the sail said that it's a perfect mast for the sail. I made my own investigation and i discovered that rrd and simmer are all progressive constant curves. From the unifiber mast selector rrd sdm masts and simmer sdm masts are perfectly matched. But the cams are not rotating well. Especially on the starboard tack even if the wind is strong. What should i do? Buy the original simmer mast? Maybe add more downhaul and less outhaul?
