  1. FVSPS Sail Course, Class 5

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

  3. What Are We DoingIn-Class Today? - Prior OTW, Discuss - Questions, Sec. 3, 4, 5 - Sail Book, Sec. 7, 8, 12 - 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. Prior OTW, Discuss 1. What did you learn? 2. What went right? 3. What went wrong?

  6. Questions/ClarificationSail Sections 3, 4, 5 Section 3 Section 4 Section 5

  7. FVSPS Sail CourseSail Book, Section 12 Tuning the Rig (Section 12, Sail book)

  8. Rig Tuning, Overview - Brion Toss quote, Rigger’s Apprentice, p. 272 - Rigging Issues: - Maintenance, Strength – Inspection/Tuning - Performance – Tuning

  9. Turnbuckle,Chainplate

  10. Rig Tuning, Tools - Diagnostic Tools: - Sight up the mast - Measure wire tension with gauge - When heeled over under sail – sight and check tension - Adjustment tools: - Wrench - Your hand

  11. Rig Tuning, Procedures - Mast centered athwart ship - Mast vertical - Stays appropriately tensioned - Check under sail

  12. Rig Tuning,Performance Implications - Mast bend - Flatten mainsail vs. add draft - Tension backstay (esp. on fractional rig) to flatten mainsail - Mast tilt - Aft rake increases weather helm

  13. FVSPS Sail CourseSail Book, Section 7 Stability (Section 7, Sail book)

  14. Stability - Will the boat, when heeling, come back up? - True or not: “Sailboats are made to heel?” - Compare keel boat vs. sailing dinghy vs. multi-hull sailboat

  15. Stability: Initial Stability - “Initial” or “Form” Stability - “Form” implies stability comes from the form of the boat, which has buoyancy that tries to right the boat - Can represent using Vectors in a Diagram - E.g. Sail book, p. 55

  16. Form Stability - How related to beam of the boat? - How related to “sea kindliness”?

  17. Stability: Ultimate Stability - How far can the boat heel and still come back upright? - “Limit of positive stability” - LOPS for the Pacific Seacraft 34 = 144 deg. - LOPS for the Hunter 41, Catalina 27 = 125 deg.

  18. Ultimate Stability - How related to beam of the boat? - How related to ballast? - How related to offshore safety?

  19. Stability: Final Comments - Compare Monohulls and Catamarans on Initial and Ultimate Stability.

  20. FVSPS Sail CourseSail Book, Section 8 Balance (Section 8, Sail book)

  21. Balance - What is Balance? - What affects Balance? - Center of Effort - Center of Lateral Resistance - See Sail, pp. 63-64

  22. Balance Issues - Dynamic Centers of Effort/Resistence - Both move foreward, but CLF moves forward faster - Result: More weather helm, with more speed/healing - Changes to make for Balance - Sail trim, shape, size - Sail, pp. 65-66 - Yawing Moment - Sail, pp. 65-66

  23. Sail Section Questions,Assignments for Next Week Section 7 Section 8 Section 12

  24. 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?
