To get the best speed when tacking and using a mainsail and jib, how should the sails should be trimmed?

Correct Answer: Option B — Trimmed so that an air slot is formed between the two sails

Aerodynamic efficiency in sailing relies on the slot effect, where the jib directs high-velocity airflow over the leeward side of the mainsail. This creates a pressure differential that enhances lift and reduces drag. Proper trimming to maintain this air slot is essential for maximizing speed and pointing ability while tacking.
