Which mechanism improved sailing ship speed using a fore-and-aft rig setup in the 15th century?

💡 Explanation

When using a fore-and-aft rig, enhanced wind capture occurs because the sails can be angled closer to the wind, generating lift, thus increasing forward propulsion. Therefore, enhanced wind capture via sail angle control occurs, rather than hull streamlining, sail area or ballast which reduce drag and increase stability but don't directly translate wind into speed.
