Stop relying on a sail until professionally assessed when cloth tears with light hand pressure, hardware or corners are pulling out, multiple seams are failing, laminate structure is separating, or reef and luff attachments are distorted. Smaller local faults may be repairable, but inspect the cause and surrounding material.
Inspect dry before hoisting
Lay the sail out clean and dry. Divide it into body, seams, corners, luff, leech, foot, reefs and previous repairs. Use consistent light and photograph both sides. Look beyond the visible tear for chafe, brittleness, distorted weave or film failure.
Inspect load-transfer areas
Corners and reef points spread concentrated loads into the body. Check rings, webbing, patches, stitching and the transition where reinforcement ends. Elongated holes, cracked resin, broken webbing or diagonal wrinkles can signal load problems.
Inspect attachments and controls
Slides, bolt ropes, luff tape, hanks, battens, cars, leech lines and UV covers affect safe use. Small attachment failures can become major damage during a hoist, reef or furl. Verify parts against the rig rather than only on the loft floor.
Inspect while loaded
Hoist in controlled conditions and observe draft, twist, leech, luff wrinkles and corner distortion. Record rig tune and control settings. A structural inspection cannot reveal every aerodynamic problem, while a good-looking flying shape cannot prove hidden strength.
Decision table
| Zone | Amber warning | Red warning |
|---|---|---|
| Body cloth | Local abrasion or pinholes | Brittle tearing or widespread separation |
| Stitching | Isolated broken thread | Multiple seam rows failing |
| Corners | Local surface wear | Ring/webbing pulling out |
| Reefs | Chafe or damaged cringle | Distortion through patch/body |
| Luff/leech | Cover or tape wear | Attachment failure or uncontrolled tearing |
What to put in the brief
- Body cloth and films
- Every seam row
- Head, tack and clew
- All reef points
- Luff tape, hanks or slides
- Leech, foot and control lines
- Battens and pockets
- Previous repairs and UV protection
Frequently asked questions
Can I use a tear test myself?
Avoid destructive tests on serviceable areas. A sailmaker can assess material using experience and appropriate methods.
Are pinholes in a spinnaker serious?
Small holes may be locally repairable, but inspect for snag points and wider fabric degradation.
What does a hooked leech mean?
It may result from shrinkage, seam or shape changes, leech-line tension or trim. Diagnose under repeatable sailing conditions.
Should I sail with damaged reef points?
Do not load damaged reef hardware or reinforcement until professionally assessed.
