During sail changes, the ability to lead twin sheets allows for the option of hoisting the new jib before lowering the old one.
Additionally, the hour-glass sheave and tilting cage allow for line entrance and exit angles of as much as 15¡ to either side of the track. This increases the options for sheet leads and winch placement.
