Maximizing performance and effective sailing of asymmetrical spinnakers requires unique sail and boat trim. It is often paired with a Spinnaker chute. Since the 1960s many faster sailing craft, starting with catamaran classes, had discovered that it is faster to sail downwind on a series of broad reaches with efficient airflow across the sail rather than directly downwind with the sails stalled. This technique had developed to the extent that in bar
