6. Questions/Clarifications Sections 7, 8, 12

7. FVSPS Sail Course
Wind
Sail Book, Section 9

8. Section 9, Wind, Overview Two Separate Topics: - Weather (pp. 69-72)
- Analysis of Wind and Boat Movement (pp )

9. Weather - Recommendation: Take USPS Weather Course
- Sea Breeze, Land Breeze (pp )
- Beaufort Wind Scale (p. 71)

10. Analysis of Wind and Boat Movement
- True Wind
- Boat Wind
- Apparent Wind

11. True vs. Apparent Wind
- Simple Situations: Directions of True Wind and Apparent Wind Parallel
- Not Parallel Situations: Analyze with Trigonometry, Diagrams
- Sail Book, pp

12. True vs. Apparent Wind: Some Implications
- Why a Beam Reach takes us Downwind (Fig. 9-9/10, p. 75)
- Why When We Tack we Tack Further than we Expect (Fig. 9-8, p. 74)

14. Apparent Wind: Decompose into Forward and Sideways Components
- Use Triangle Diagrams (Fig. 9-12, p. 76)
- Why Boats heel most on a Close Haul (p. 77)
- Implications for Sail Trim (Fig. 9-15, p. 78)

15. Sail Trim: Goal, Rules of Thumb
- Want to Keep Sail at Same Angle of Attack when in Pull Mode (Fig. 9-15, p. 78; Fig. 10-3, p. 84)
- “When in doubt, let it out” (Summary, p. 79, end)

16. FVSPS Sail Course
Sail Shape
Sail Book, Section 10

17. Sail Shape, Basic Concepts
Angle of Attack
Laminar Flow over Sail
Using Telltales to Assess Angle of Attack, Whether Air Flow is Laminar

18. Sail Shape, Major Adjustments
Angle of Attack: Sheets/Helm Adjustment
Draft: mainsail outhaul, sheets, halyards, cunningham
Basic Rule: Flatten Sail to De-Power (in Pull Mode)

19. Sail Shape, Twist Adjustments
Headsail: Placement of Genoa Car
Mainsail: Boomvang, Traveller, Sheet

20. Sail Shape: Understanding Twist
Wind Gradient
Effect of Stronger True Wind on Apparent Wind
Need for Sail Twist to Keep Same Angle of Attack

21. Understanding Twist: Sail Book Errors
P. 86, par. 16
P. 86, par. 17

22. FVSPS Sail Course
