2010 WARP F2009 5.2 - 12.0

With the WARP F2009 Kai Hopf introduced a revolutionary way to engineer contour into the sail. We call this the INDEPENDANT.SHAPING.CONCEPT. Instead of using just one kind of shape for the whole sail (body and sleeve), Kai now works with 2 separate and independent profiles for the sail body and the sleeve. Despite taking twice the design time to perfect the advantages of this shaping concept are a break-through in sail design that also enables Kai to create different cloth tensions in these 2 ‘Independent’ parts of the sail:

1. The sail body tension is still pretty high and oriented towards the internal leading edge. Through the leading edge oriented sail body shaping the WARP F2009 rotates even better than its predecessor and gave significant benefits in high-end control.
2. Independent shaping enables us to use much lower tension for the mast sleeve area. The dynamic benefits are clear, especially when accelerating at the start-line or after jibing, or going through lulls, since it demands far less wind pressure to gain momentum. As a result the new WARP is now a lot less physical to sail.
