Overview
Good trim maximizes drive with minimal drag. Trim until the luff just stops fluttering, then fine-tune to keep telltales streaming.
Objectives
- Use luffing as a cue to sheet in or steer down.
- Read telltales to balance power and angle of attack.
- Retune after maneuvers and gusts.
Key Concepts
- Luffing: sheet in or bear away.
- Stall: over-trimmed; flow separates.
- Telltales: both streaming = fast; windward lifting = ease; leeward lifting = trim in.
Drills
- From luffing, trim in slowly until flow attaches.
- Ease a touch in puffs to keep speed.
- Re-trim within seconds after turns.
Common Mistakes
- Trimming once and forgetting.
- Over-trimming upwind.
- Not easing in puffs, causing heel.
