A moderate width sleeve, 7 battens, and 3 cams provide draft stability through a huge wind range. Combined with a higher aspect ratio, the Severne OverDrive M4 has impeccable handling characteristics; a lightweight feel, with softer flex.
Smaller sizes (5.5 and down) have 6 battens to increase flex and control for when conditions get extreme.
The OverDrive M4 benefits directly from advances made on the Mach4 development. Higher aspect ratios and increased leverage add to the efficiency. Flow aligned battens further improve aerodynamics. The resulting performance is explosive acceleration and big numbers on the GPS.
The OverDrive M4 can be run on either RDM masts or SDM masts.
