Hey guys I'm looking at buying a second hand 2013 Severne Turbo 6.5m. But am not sure if it would be compatible with my masts. I have searched the web and forum for answers but have found a lot of conflicting opinions. My masts are 430 SDM Constant Curve 21 IMCS, a North red series SDM 35% carbon & a Sunshine Constant Curve 30% carbon. If there is anyone out there in the know, Id appreciate your opinion please. I'd especially like to hear from guys who have used this sail. Thanks, Ken.
