The VMG is Aerotechs all out race sail. This model has been tweaked on the winning ways of the earlier model. With even more shape and double vertical shaping panels you will find it has an even wider range while maintaining the slippery feel that the VMG stands for. The exclusive use of exotic materials (and no monofilm) for the construction allows weights to be kept to a minimum and performance kept to a maximum. Construction: This sail is built out of 100% grid monofilm and features an ultra light weight Pentex center panel. Other features include; roller bearing camber inducers, a thermo-formed base pad, a new raised stainless steel 6-1 pulley with oversized rollers, and an interactive rigging guide. We use a mix of carbon tubular battens and rod battens in this sail.
