Rolly Tasker Sails builds Cruising Code Zeros to give extra performance in light winds in particular for modern boats with non overlapping genoas.
Cruising Code Zeros are designed with straight luff incorporating an anti-torsion rope and a small positive roach for stable trim and easy handling. They can be built out of heavy spinnaker cloth, which is most competitive, or a laminate for more demanding cruising sailors.
Race Code Zeros are built out of Dimension Polyant CZ Laminate. The mid girth of Racing Code Zeros is designed to be 75% of foot to avoid rating penalties which does mean a small downturn in wind range and handling but this is accepted by racers because of the advantages in rating.
