Dead-end fitting for a Code Zero halyard.

Code Zero halyard with 2:1 purchase
To boost the performance when using a Code Zero , the halyard load must be higher than what normal halyard boxes and stoppers can handle. Therefore, a 2:1 purchase needs to be arranged by fixing the dead end of the halyard in the mast and letting it run through a block attached to the halyard swivel. Position on the mast must be specified by Seldén. In most cases Code Zero sails need to be hoisted lower than gennakers and spinnakers.
