The Z-4 is optimized for lighter winds. It has the same maximum roach of the Z-3H but is slightly fuller and made of a new Contender cloth with a slightly revised panel layout. The Z-4 has more shaping right under the full batten but with the lighter cloth and increased panel rock down low it should have more power in light wind and still have a good range. We are now making the Z-4 standard with a folded leech but it can also be made with a hot cut leech.
