How Sail Controls Affect Sail Shape and Power

21. List jib controls and describe impact on angle of attack, depth, draft position, and twist.

22. Describe the impact of jib fairlead position on telltale behavior and the flaw of “even break”.

23. List mainsail controls and describe the impact on angle of attack, depth, draft position, and twist.

24. Explain how boatspeed, pointing ability, heel, and weather helm can be affected by sail trim.

25. Describe the techniques for maximizing sail power in light air by adjusting sail controls and helm.

26. Describe how changes in boom vang tension impact mainsail shape and power when sailing on a reach.

SKILLS

Safety: Preparation & Procedures

27. Demonstrate proper use of a winch, winch handle, and handling lines wrapped around a winch.

28. Demonstrate a COB Figure-8 and Quick-Stop recovery in each crew position using proper communication and demonstrating teamwork

Boat Handling

29. Demonstrate proper technique to rig and get underway, stow and coil for easy release, and proper dropping and stowing of sails.

30. Demonstrate proper driver position and helm technique, including the use of a tiller extension.

32. Demonstrate how to sail with the tiller tied off, using weight and trim at both full-speed and down speed.

33. Demonstrate proper jibing in each crew position from a broad reach to a broad reach including commands, rate of turn, handling the helm, weight movement, and proper exit angle.

34. Demonstrate how to come out of irons by sailing backwards and then backing the jib to exit the no sail zone.
