  1. 1. Sailing Downwind Presented by Forespar www.Forespar.com Presenter: Bruce Brown
  2. 2. Sailing Downwind • Topics for this presentation – Direction of the wind • Apparent Wind Direction • True Wind Direction • Why the difference matters – Sails • Jib/Genoa or Jib Top • Asymmetrical Spinnaker • Spinnaker • Mainsail – Techniques for deploying and trimming – Techniques for steering
  3. 3. Efficient Downwind Sailing • Understand the wind • Understand the waves • Understand your boat • Tailor your expectations to the boat and conditions you experience
  4. 4. Wind Direction Apparent Wind Direction and Apparent Wind Speed • What you feel from the deck • Made up of true wind direction plus the wind created by the boat moving through the air. True Wind Direction and True Wind Speed • This is the wind you feel when the boat is not moving at all
  5. 5. Understanding waves
  6. 6. Understand your boat • Focus on balanced sail plans. • Keep the sail selection so the boat is under control • OK to reef • OK to reduce headsail size
  7. 7. Understand your boat • Displacement mono- hulls are limited to hull speed when sailing downwind. • Sail plan must be controllable • In heavy air – one can reduce sail to slow down.
  8. 8. Understand your boat • Light displacement mono-hulls can surf and can minimize apparent wind speed • Sail plan must be controllable • Weight location may be critical to control and comfort
  9. 9. Understand your boat • Split Rigs allow for multiple sail options • Location of center of effort is important to balance of the boat • Reducing sail area is OK • Bring sail plan to center of boat as wind speed increases to maintain control
  10. 10. Understand your boat • Multihulls will often sail at higher wind angles (apparent wind) as they sail at higher speeds downwind • Sails are often flatter • Apparent wind speed is often higher on multihulls when sailing downwind
  11. 11. Sailing Downwind - Comfort • Boat rocks back and forth – Cause – Solution • Sails collapse – Cause – Solution • May need to gybe – Sail your angles – Suggestions for gybing
  12. 12. Sailing Downwind - Comfort • Boat rocks back and forth – Cause – Solution • Sails collapse – Cause – Solution • May need to gybe – Sail your angles – Suggestions for gybing
  13. 13. Sailing Downwind - Comfort • Boat rocks back and forth – Cause – Solution • Sails collapse – Cause – Solution • May need to gybe – Sail your angles – Suggestions for gybing
  14. 14. Sailing Downwind - Comfort • Boat rocks back and forth – Cause – Solution • Sails collapse – Cause – Solution • May need to gybe – Sail your angles – Suggestions for gybing
  15. 15. Sailing Downwind – How to start • Jib • Asymmetrical • Symmetrical Spinnaker • Split Rig
  16. 16. Jib or Asymmetrical • Reduce the size of the jib prior to turning downwind • This makes any movement on the foredeck easier with less hassle!
  17. 17. A Whisker Pole using a Jib, Genoa or a Jib Top • Hook the lazy sheet to the whisker pole • Hoist the whisker pole topping lift • Turn down wind to 145 or 150 degrees apparent • Pull on the lazy sheet to bring the jib over onto the windward side • Trim the whisker pole so it is about parallel to the boom – as you head up – the boom comes in – so the pole goes forward • As you fall off – the boom goes out – so the pole comes aft.
  18. 18. Asymmetrical • Control Methods for hoist and douse – Spinnaker Sock – Top Down Furler
  19. 19. Asymmetrical • Control Methods for hoist and douse – Spinnaker Sock – Top Down Furler
  20. 20. Asymmetrical • Control Methods for hoist and douse – Spinnaker Sock – Top Down Furler
  21. 21. Asymmetrical • Control Methods for hoist and douse – Spinnaker Sock – Top Down Furler
  22. 22. Asymmetrical • Control Methods for hoist and douse – Spinnaker Sock – Top Down Furler
  23. 23. Asymmetrical • Trim – When in doubt, let it out! – Don’t strap the sail – Maintain halyard tension when reaching – Let if fly with less halyard tension when deeper downwind.
  24. 24. Symmetrical Spinnaker • Spinnaker Sock – Set every piece of hardware up before hoisting the sail • Pole • Afterguy • Foreguy • Toping Lift • Sheets
  25. 25. Symmetrical Spinnaker • Spinnaker Sock – Set every piece of hardware up before hoisting the sail • Pole • Afterguy • Foreguy • Toping Lift • Sheets • Each part controls the corners of the spinnaker • Halyard – Head • Sheet – Clew • Afterguy – Tack • Pole – Position controlled by: o Topping Lift o Foreguy
  26. 26. Symmetrical Spinnaker • Halyard – Head • Sheet – Clew • Afterguy – Tack – Pole • Toping Lift • Foreguy
  27. 27. Symmetrical Spinnaker • Hoisting – Spinnaker must be packed with all the edges clear of wraps • Run the tapes – Be sure the sail can be controlled during the hoist • Spinnaker Sock • Stops
  28. 28. Symmetrical Spinnaker • Hoisting – Spinnaker must be packed with all the edges clear of wraps • Run the tapes – Be sure the sail can be controlled during the hoist • Spinnaker Sock • Stops
  29. 29. Symmetrical Spinnaker • Trimming – Once fully hoisted • Open the spinnaker sock • Bring the pole back as the sheet gets trimmed • Level the pole height to parallel with the water – Clews should be the same height off the water • Pole location should be close to parallel to boom • Trim so the luff just curls
  30. 30. Steering • Steady course allows trim to remain constant • Steer to the wind and use the waves to help • When the boat seems to rock back and forth and seems to be oscillating too much: Steer less!
  31. 31. Steering • Steer less! • When the mast moves to windward: • Steer into the oscillation (in the direction of the masthead) until the mast reaches vertical – then center the helm. • This will stop the rock and roll you are experiencing!
