Do this today

  • Practice the "Height Lock" drill — 60 seconds of locked height to feel balance
  • Work on finding your VMG angle — use the "too high vs too low" indicators
  • Practice 10 gybes focusing on smooth entry, transition, and exit
  • Focus on apparent wind management — feel the wind on your face, not just the true wind
  • Work on core technique cues: body position, sheet trim, and weight distribution
Common Mistakes
  • • Over-sheeting — kills speed and makes the sail feel heavy
  • • Sailing too high — you're going fast but not toward the mark
  • • Sailing too low — you're going toward the mark but too slow
  • • Rushing gybes — smooth and controlled is faster than rushed
  • • Ignoring apparent wind — true wind direction doesn't matter, apparent wind does
  • • Poor body position — leaning too far forward or back kills balance and speed

Downwind = Apparent Wind Management

On foil downwind, you're moving fast—often faster than the true wind speed. This means the apparent wind (the wind you feel) comes from ahead, not behind. You're essentially sailing upwind relative to the apparent wind, even though you're going downwind relative to the true wind.

Apparent Wind vs True Wind
True wind: The actual wind direction and speed. Apparent wind: The wind you feel on your face while moving. On foil downwind, apparent wind is forward of the beam—often 30-60° forward of your course.
Why It Matters
You need to trim and angle your sail relative to apparent wind, not true wind. If you sheet out too much (thinking you're going downwind), you'll lose power. Sheet in more than you think—you're essentially sailing upwind to the apparent wind.
Feel the Wind
The best way to manage apparent wind is to feel it on your face and body. If the wind feels like it's coming from ahead, sheet in. If it feels like it's coming from behind, you're probably going too slow or sailing too low.

Core Technique Cues

Downwind technique on foil requires specific body positioning, sheet management, and weight distribution. Focus on these cues to improve your performance.

Body Position
Weight forward: Drive your weight forward to keep the foil flying and maintain speed
Knees bent: Stay low and balanced—don't stand too tall
Hips forward: Push your hips forward to maintain foil angle and prevent pitch-up
Relaxed upper body: Don't fight the sail—let it work for you
Sheet Trim
Sheet in more than you think: Apparent wind is forward, so you need more sheet tension
Feel the power: The sail should feel powerful, not floppy
Small adjustments: Make small sheet changes to optimize—don't over-sheet or under-sheet
Match conditions: More sheet in stronger wind, slightly less in lighter wind
Weight Distribution
Front foot pressure: More pressure on front foot to drive the foil forward
Balance: Stay balanced—don't lean too far forward or back
Dynamic adjustment: Shift weight as conditions change—forward in gusts, slightly back in lulls
Quick Fix
Over-sheeting kills speed: If your sail feels heavy and you're losing speed, ease the sheet slightly. The sail should feel powerful but not over-powered. You want to feel the power, not fight it. If you're constantly fighting the sail, you're over-sheeted.

Finding VMG (Too High vs Too Low Indicators)

VMG (Velocity Made Good) is your speed toward the mark. The optimal angle balances speed and course. Too high = fast but not toward the mark. Too low = toward the mark but too slow. Find the sweet spot.

Too High (Sailing Too High)
You're going fast but not making progress toward the mark
Apparent wind feels like it's coming from well ahead
You're sailing a longer distance to the mark
Fix: Bear away slightly (sail lower) to find better VMG
Optimal VMG (Sweet Spot)
You're going fast AND making good progress toward the mark
Apparent wind feels balanced—not too far ahead, not behind
You're maintaining foil speed while sailing an efficient course
This is your target angle—maintain it and adjust as conditions change
Too Low (Sailing Too Low)
You're going toward the mark but losing speed
Apparent wind feels like it's coming from behind or the side
You're struggling to maintain foil speed
Fix: Head up slightly (sail higher) to regain speed and find better VMG
How to Find Your VMG
Start by sailing slightly too high, then gradually bear away until you feel like you're losing speed. The sweet spot is just before you start losing speed. Use your GPS or feel—if you're going fast but not making progress, you're too high. If you're making progress but losing speed, you're too low.

Gybes: Make Them Boring

Good gybes are smooth, controlled, and boring. No drama, no big movements, just a systematic transition from one tack to the other. Break the gybe into three phases: entry, transition, and exit.

Entry Phase
Set up early: Start the gybe when you're ready, not when you're forced
Maintain speed: Keep foil speed through the entry—don't slow down
Bear away smoothly: Start bearing away gradually, not abruptly
Prepare your body: Get ready to move—weight forward, knees bent
Transition Phase
Move the sail: Sheet out and move the sail across smoothly—don't rush
Step across: Step across the board smoothly—one foot at a time
Keep the foil flying: Maintain foil speed—don't let it drop
Stay balanced: Keep your weight forward and balanced
Exit Phase
Sheet in: Sheet in smoothly as you exit—don't over-sheet
Find your angle: Head up to your optimal VMG angle
Maintain speed: Keep foil speed—you should exit at full speed
Get back to sailing: Return to your normal downwind technique immediately
Common Gybe Mistakes
Rushing: Smooth is fast. Don't rush the transition. Slowing down: Maintain foil speed through the entire gybe. Over-sheeting on exit: Sheet in smoothly, not aggressively. Poor body position: Stay balanced and forward—don't lean back.

3 Drills

Practice these drills to improve your downwind technique. Each drill focuses on a specific skill that translates to better race performance.

1. Height Lock Drill
Purpose:
Develop body control and feel for balance without constantly adjusting your course.
How to do it:
• Set your course angle (find your VMG)
• Lock your course—don't change angle for the duration
• Sail for 60 seconds (or 90 seconds for advanced)
• Focus on controlling the foil with your body weight and sheet trim only
• Feel how small weight shifts affect balance and speed
Timer Suggestions:
Beginner: 30-45 seconds | Intermediate: 60 seconds | Advanced: 90-120 seconds
2. Angle Ladder Drill
Purpose:
Learn to feel the difference between too high, optimal VMG, and too low. Develop your sense of optimal angle.
How to do it:
• Start by sailing too high (you'll feel fast but not making progress)
• Gradually bear away (sail lower) in 5-10° increments
• At each angle, sail for 20-30 seconds and feel the difference
• Continue until you feel like you're losing speed (too low)
• Head back up to find the sweet spot (optimal VMG)
• Repeat 3-5 times in a session
Timer Suggestions:
Each angle: 20-30 seconds | Full cycle: 3-5 minutes | Repeat: 3-5 cycles per session
3. Gybe Set Drill
Purpose:
Practice gybes systematically. Focus on smooth entry, transition, and exit. Make gybes boring and consistent.
How to do it:
• Set up a downwind course (use two marks or visual references)
• Sail downwind, execute a gybe, continue downwind
• Focus on one phase at a time: entry, then transition, then exit
• After each gybe, assess: Was it smooth? Did I maintain speed? Was it boring?
• Do 10-15 gybes in a session
Timer Suggestions:
Per gybe: Focus on smooth execution, not speed | Set of 5: Rest 30 seconds between sets | Total: 10-15 gybes per session
