  1. FVSPS Sail Course, Class 3

  2. Today’s OTW • Weather Outlook • Boats Going Out • Sign-Up Sheet

  3. What Are We DoingIn-Class Today? - Prior OTW, Discuss - Questions, Sec. 13-15 - Basic Sailing Concepts, Procedures - Sail Book, Sec. 9-11 - OTW Assignment

  4. Yacht Club Bar Song, Chorus I love to sit around the yacht club bar and talk about the things we’re going to do. I love to sit around the yacht club bar because it doesn’t move. The swells are big and the winds are high but that don’t bother me. Cause I never get lost and my tummy doesn’t toss It’s a wonderful life on the sea.

  5. Yacht Club Bar Song, Verse 3 My head it was a reeling, my feet got tangled up. Those damn old sheets were everywhere, just trying to trip me up. The halyard broke, the boom fell down, the main took off like a bird. Mayday was my final cry as I dived beneath my berth.

  6. Yacht Club Bar Song, Chorus I love to sit around the yacht club bar and talk about the things we’re going to do. I love to sit around the yacht club bar because it doesn’t move. The swells are big and the winds are high but that don’t bother me. Cause I never get lost and my tummy doesn’t toss It’s a wonderful life on the sea.

  7. Prior OTW, Discuss 1. What did you learn? 2. What went right? 3. What went wrong?

  8. Questions/ClarificationSail Sections 13, 14, 15 Section 13 Section 14 Section 15

  9. Tying Boat to the Dock • Basic Keelboat, p. 49

  10. Sail Balance • Basic Keelboat, p. 52 • Sail, Section 8 • Weather helm vs. lee helm

  11. Heaving ToBasic Keelboat, p. 45; Sail, p. 144

  12. FVSPS Sail Course Wind Sail Book, Section 9

  13. Section 9, Wind, Overview Two Separate Topics: - Weather (pp. 69-72) - Analysis of Wind and Boat Movement (pp. 72-79)

  14. Weather - Recommendation: Take USPS Weather Course - Sea Breeze, Land Breeze (pp. 69-72) - Beaufort Wind Scale (p. 71)

  15. Analysis of Wind andBoat Movement - True Wind - Boat Wind - Apparent Wind

  16. True vs. Apparent Wind - Simple Situations: Directions of True Wind and Apparent Wind Parallel - Not Parallel Situations: Analyze with Trigonometry, Diagrams - Sail Book, pp. 74-75

  17. 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)

  18. A Beam Reach Takes Us Downwind Figure 9-9, p. 75 Figure 9-10, p. 75

  19. When We Tack We Tack Further than we Expect Figure 9-8, p. 74

  20. Apparent Wind: Decompose intoForward 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)

  21. Decompose Wind Force Into Drive Force And Lateral Force Figure 9-12, p. 76

  22. Why Boats Heel Most on a Close Haul Figure 9-13, p. 77

  23. Implications for Sail Trim Figure 9-15, p. 78

  24. Sail Trim:Goal, Rules of Thumb - Want to Keep Sail at Same Angle of Attack when in Pull Mode (Fig. 9-16, p. 79; Fig. 10-3, p. 84) - “When in doubt, let it out” (Summary, p. 79, end)

  25. Angle of Attack, Boom Angle to Apparent Wind, Is Constant Figure 9-16, p. 79

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

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

  28. 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)

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

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

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

  32. FVSPS Sail Course Preparing to Sail Sail Book, Section 11

  33. Stepping the Mast

  34. Preparing to Sail • Check the weather. • Reefing? • Headsail choice? • Have the proper clothing, footwear. • Bring any needed food and water.

  35. Crew Activities, Departing (review) Remove canvas, instrument covers. Hank-on headsail. Tie/run jib sheets. Run main sheet. Attach halyards. Untie dock lines. Stow fenders. Close life-line gate.

  36. Sailing Activities Hoist mainsail. Hoist/unfurl headsail. SAIL! Deploy lazy jacks. Drop/furl headsail. Drop/flake mainsail.

  37. Crew Activities, Returning (review) Open life-line gate. Deploy fenders. Positioned to step quickly off onto dock. Tie Boat to the dock (Basic Keelboat, p. 49). Fold/bag headsail. Remove/coil jib sheets. Flake mainsail, stow lazy jacks. Stow main sheet. Position canvas, instrument covers.

  38. Sail Section Questions,Assignments for Next Week Section 9 Section 10 Section 11

  39. OTW Today Up-dated weather briefing? List of people who want to sail today Assignments to boats will be forthcoming shortly during lunch period. Any announcements from the captains?
