On the larger sizes of Turbo GT both cams are below the boom. This locks the power zone very low in the sail where it can most easily be controlled. Swing weight is also improved by lowering all the hardware and allowing the upper sections to flex and exhaust freely.
The Turbo GT is designed to be rigged on either RDM masts or SDM. Incredible rotation is the advantage on the RDM mast, and increased stability is the benefit of an SDM mast. Both options will deliver blazing speed, early planing and an ultralight feel.
The Turbo GT is delivered with an RDM cam for sail sizes 5.5, 6.0 and 6.5. The 7.0, 7.5, 8.1, 8.6 and 9.2 come with two SDM cams.
