Efficient Downwind Sailing Understand the wind Understand the waves Understand your boat Tailor your expecta?ons to the boat and condi?ons you experience
Wind Direc?on Apparent Wind Direc3on and Apparent Wind Speed What you feel from the deck Made up of true wind direc?on plus the wind created by the boat moving through the air. True Wind Direc3on and True Wind Speed This is the wind you feel when the boat is not moving at all
Understanding waves
Understand your boat Focus on balanced sail plans. Keep the sail selec?on so the boat is under control OK to reef OK to reduce headsail size
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.
Understand your boat Light displacement mono- hulls can surf and can minimize apparent wind speed Sail plan must be controllable Weight loca?on may be cri?cal to control and comfort
Understand your boat Split Rigs allow for mul?ple sail op?ons Loca?on 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
Understand your boat Mul?hulls will o[en sail at higher wind angles (apparent wind) as they sail at higher speeds downwind Sails are o[en flader Apparent wind speed is o[en higher on mul?hulls when sailing downwind

Sailing Downwind How to start Jib Asymmetrical Symmetrical Spinnaker Split Rig
Jib or Asymmetrical Reduce the size of the jib prior to turning downwind This makes any movement on the foredeck easier with less hassle!

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.

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 loca?on should be close to parallel to boom Trim so the luff just curls
Which Downwind sails to use? Wind Speed Apparent Wind Direc?on Specifics of Boat Crew experience Balance the boat Be aware of changes in wind speed and direc?on Split Rigs
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 oscilla?ng too much: Steer less!
Steering Steer less! When the mast moves to windward: Steer into the oscilla?on (in the direc?on of the masthead) un?l the mast reaches ver?cal then center the helm. This will stop the rock and roll you are experiencing!
