Developing the All Around Star 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 14, we utilized our 3D computer designs and Computation Fluid Dynamics (CFD) to optimize for all around performance.
The CFD modeling showed us that 40% of the forward driving force is generated by the Star headsail while sailing close-hauled. With the aid of CFD modeling, we developed the J6 jib that has all the gears high and fast in all conditions. The performance in two boat testing was better than we could have ever hoped for in pairing the powerful high pointing J6R Jib with the low drag all around M14+ Main. The J6R Jib is our newest flatter bi-radial medium/heavy air jib built from heavier materials for shape holding and durability in fresher conditions.
For the 2012 Olympics, Mark Mendelblatt and Brian Fatih selected the M14+ main (plus for extended range) and J8H crosscut jib for light/medium conditions and J6R bi-radial jib for medium/heavy conditions.
To cope with the wide range of wind speeds and conditions expected in Weymouth, we reduced the total luff curve on the M14 design to flatten the main without losing too much of the power that had worked so well at the qualifiers in Perth.
The M14+ proved to have enough grunt in max power conditions and was much easier to depower in the fresher conditions.
The flatter luff curve also helped in lighter conditions from getting too deep and shut down at the top batten. The M14+ is the best all purpose design we have developed and performs well in all conditions upwind and down.
The M14+ main combined with J8H and J6R jibs performed well in 2012 and will be well suited for Miami winter series and Southern California conditions.
We also offer our most powerful and proven J7C full jib, which is well suited for Newport Beach NA's and San Diego World's conditions, paired with either a J8H or J6R. For most conditions the J8H and J6R both perform well as all purpose jibs.
