Developing the All Around Main and Jib

The focus of our Main and Jib development began with evaluating the existing "state-of-the-art" products and deciding what we could do better.

The challenge of designing the All Around Star Main is to have a main with enough power for 6-10 knots upwind while not being too deep and shut down for the real light and/or too full for the fresher conditions on a very flexible spar. All these upwind range issues are then balanced with still having a fast, full and open enough main downwind on a boat with no spinnaker and a small jib. With each of our prototype main designs 1 thru 11 we utilized our 3D computer designs and Computation Fluid Dynamics (CFD) to optimize for all around performance.

The CFD testing has shown that 40% of the forward driving force is generated by the Star headsail while sailing closehauled. With the aid of CFD modeling, we have developed a new all around J7 jib that has all the gears high and fast in all conditions. The performance in two boat testing is better than we could have ever hoped for in pairing the powerful high pointing J7 Jib with the low drag all around M11 Main. The J6R Jib is the flatter bi-radial heavy air jib built from heavier materials for shape holding and durability in heavy air conditions.
