- 10. ©2018 Edward Herlihy Allrights reserved Sails – The boat’s engine P21 • Main Sail – Reef Points – Streamers • Head Sail/Foresail – Jib – Genoa – Telltales Forestay or Headstay Foresail or Headsail Backstay JibGenoa Foot Luff TackClew Head Battens
- 11. ©2018 Edward Herlihy Allrights reserved Rigging P22 • Standing Rigging – Keeps the mast up • Running Rigging – Controls the sails
- 12. ©2018 Edward Herlihy Allrights reserved Running Rigging: Basic Sail Controls • Halyards – ignition key • Sheets – throttle – Luffing is a flutter along the leading edge or luff of the sail. It is quiet. – Flogging is the whole sail whipping about like a flag. It is noisy. – "When Freaking Out - Let It Out!” – "When In Doubt - Let It Out!“ • Outhaul – – Flattens and depowers the sail
- 13. ©2018 Edward Herlihy Allrights reserved Winches P34 • Allow you to exert great force on a line • Self Tailing or not • Single Speed / Two Speed • ALWAYS wrap in Clockwise direction – Keep your fingers from getting caught! – Three or four wraps – Over guide and into cleat – Then use a handle – Remove handle after use Drum Base GuideCleat Handle Drive Hole
- 14. ©2018 Edward Herlihy Allrights reserved Raising the Sails P37 • Raise the mainsail first – Remove and stow sailcover – Connect halyard shackle to headboard – 5 lines to release: • Sheet ● Vang • Reefing ● Halyard • Sailties LAST – Haul on the halyard • Unfurl or raise the jib – Furling line – Halyard • Hanks TO UNFURL PULL ON JIB SHEETS TO FURL PULL ON JIB FURLING LINE
- 15. ©2018 Edward Herlihy Allrights reserved Wind – fuel for the sails • Varies in strength and direction. • How do you find where the wind is coming from?
- 16. ©2018 Edward Herlihy Allrights reserved Managing the Sails: • “Trim” – increase tension on a working sheet • “Ease” – let some tension out of a working sheet • “Blow” – release a working sheet • Manage the jib from the LEEWARD side of the boat • Sails are “SET” when they have the proper tension on their working sheets
- 17. ©2018 Edward Herlihy Allrights reserved Sails are Wind Benders • Sails can generate 1/3 of their power from PUSH • Sails can generate 2/3 of their power from PULL – Sails are most efficient when there is LAMINAR air flow across them. • When sailing upwind all power is PULL • When sailing across the wind power is a combination of PUSH & PULL • When sailing downwind power is only PUSH Coanda Effect (1910) WING FASTER moving air ... LESS Pressure SLOWER moving air ... MORE Pressure Bernoulli’s Principle (1738)
- 18. ©2018 Edward Herlihy Allrights reserved Points of Sail • Luffing Arc / No Go Zone - ~45º on either side of the "Eye of the Wind". In the center of the luffing arc is IRONS or THE EYE OF THE WIND. • Sail Trim: – Close Hauled – all in – Close Reach - 1/4 Out – Beam Reach - 1/2 Out – Broad Reach - 3/4 Out – Run - All Out • Avoid luffing sails and over trimming • Ease sails until sails luff, then trim in. • "When Freaking Out - Let It Out!” • "When In Doubt - Let It Out!" Up and In Down & Out
- 19. ©2018 Edward Herlihy Allrights reserved Steering a boat with a tiller • Helmsperson usually sits opposite the sail (and boom) – Visibility - Can see mainsail and ahead – Balance – Counterweight to the force on the sail • Helmsperson must CHANGE SIDES when the sail changes sides (Tacks or Gybes) • Head Up / Go Above (positive) – Push tiller toward boom • Fall Off / Go Below (negative) – Pull tiller away from boom
- 20. ©2018 Edward Herlihy Allrights reserved Steering a boat with a tiller Tacking (TTT) P48-49 Turning the bow of the boat through the wind from CLOSE HAULED point of sail. 1. Look around - situational awareness - plan your tack. 2. HELM: "Make Ready to Tack" / "Ready About" / "Prepare to Tack“ 3. CREW: uncleat jib sheet, and prepare to trim on opposite side 4. CREW: "READY!“ 5. HELM: Sight 90º over your shoulder - Pick a specific object 6. HELM: "Tacking" / "Coming About“ 7. HELM: Push Tiller slightly toward BOOM. (Tiller Toward Tack). Boat will begin to turn 8. HELM: When Main & Boom flog, change side of boat WHILE LOOKING FORWARD. (pass tiller behind your back) 9. CREW: When Jib collapses, trim on other side 10. HELM: Stop turning (center tiller) when pointed at object from step 5.
- 21. ©2018 Edward Herlihy Allrights reserved Steering a boat with a tiller Gybing (TAG) P50-51 Turning the stern of the boat through the wind from BROAD REACH or RUN 1. Look around - situational awareness - plan your gybe. 2. HELM: "Make Ready to Gybe" / "Prepare to Gybe“ 3. CREW: Uncleat jib sheet, and prepare to trim on opposite side 4. HELM: Trim Mainsheet ALL the way in 5. CREW: "READY!“ 6. HELM: Sight a new predicted target 7. HELM: Change side of boat WHILE LOOKING FORWARD. (pass tiller behind your back) 8. HELM: Push Tiller AWAY from BOOM. (Tiller Away Gybe) Say "GYBING!“ or “GYBE HO!” 9. HELM: When boom switches sides, stop turning (center the tiller) 10. CREW: Trim jib
- 22. ©2018 Edward Herlihy Allrights reserved Getting out of “Irons” Sailing off a mooring • Back the jib on the tack that you wish to sail off on (if stbd. tack, back jib to stbd.) • The bow will blow down, and boat will turn. • Once the bow blows down to where you would be on a close reach, trim the jib with the leeward sheet, trim the main, and sail away!
