What to do at sea, what can wait until you are home, what needs a loft, and what should not be attempted at all.
At sea: stop the load
The priority is not repairing the sail. It is preventing a small problem becoming a large one, and getting the boat home safely.
Take the load off. Reef, change down, or drop the sail. A tear grows along a load path, and the load path is what you are removing.
Stop a tear spreading. A patch of sail repair tape on both sides, with the edges rounded rather than square, will hold a small tear in the body of a sail long enough to get home. Round the corners — square ones lift and peel.
Do not use tape near a corner, a reef point, or any structural area. Those are carrying real load and tape will not hold it. If a corner is failing, that sail is finished for this passage.
Do not sew a temporary repair unless you know what you are doing. A row of stitching in the wrong place creates a new stress line, and it makes the eventual proper repair harder.
Getting home
Photograph the damage before you do anything, and again after any temporary repair. What the damage looked like originally is important, and it is lost as soon as tape goes on it.
Note what happened: the conditions, what the sail was doing, whether anything preceded it. A tear that appeared while flogging, a tear that appeared after touching a spreader, and a tear that appeared with no warning are three different things.
Do not wash the sail before it is looked at. Washing removes evidence — abrasion marks, contact traces, staining — that helps identify the cause.
What can wait
Small stitching failures away from load paths. Get them done, but they are not urgent.
A worn chafe patch that has not worn through to the sail.
Cosmetic marks.
A UV strip whose stitching is starting to go — soon, but not immediately.
What cannot wait
Anything at a corner. Head, tack, clew, reef tack, reef clew. These carry the whole sail and they fail completely rather than gradually.
A seam that has begun to unzip. It will keep going.
Webbing that is damaged.
Delamination that is spreading.
A tear longer than a few centimetres, or any tear on a load path.
Stop using the sail and get it looked at.
What a loft should do
Anything structural. Corners, webbing, reinforcement, load paths.
Anything on a laminate or continuous-fibre sail beyond the most trivial. These are bonded structures and repairing them is a different craft from sewing woven cloth.
Restitching, which is routine and worth doing before seams fail.
Replacing a UV strip.
Anything you are not sure about.
What should not be attempted
Home machine sewing on a sail. A domestic machine cannot handle sailcloth, and the result is a row of holes.
Adhesives that are not sail repair products. Contact adhesive, silicone and general glues damage cloth and make proper repair difficult or impossible.
Cutting anything to make a repair fit.
Removing hardware to inspect it, unless you are confident it goes back correctly.
Alterations
Sails can sometimes be altered — recut smaller, restitched, reinforcement added, a reef added, a UV strip replaced.
Sometimes it is worth it and sometimes it is not, and the honest test is whether the cloth has life left. Altering a sail whose cloth has stretched produces a smaller version of a tired sail. Altering a sound sail whose shape or size no longer suits the boat can be excellent value.
Alterations we can advise on: adding or moving a reef, adding protection where you have found chafe, replacing a UV strip, adding reef marks, restitching, changing a corner fitting.
Alterations to be careful about: substantially recutting a sail’s shape, and changing what a sail is for. Both are more work than they sound and the result is a compromise designed around an existing sail rather than around your boat.
Local lofts
Using a loft near you for a repair is sensible, and often the only practical answer.
Two things worth doing. Tell them what the sail is — your Sail Passport has the cloth, the construction and the hardware, and a loft repairing a continuous-fibre sail needs to know that before it starts. And keep a record of what was done, with photographs, in your Passport.
If a repair might relate to a warranty question, email crew@surgesails.com before having it repaired — see Warranty and Support. A repaired sail is much harder to assess.
For an accepted warranty claim, we may ask you to return the sail or authorise a local loft. SurgeSails pays the agreed return shipping or an approved local repair. Non-warranty repair and shipping costs are yours. In either case, agree the work before it begins and add the completed repair to the Sail Passport.
Fix the cause
A sail that chafed in one place will chafe there again. A batten pocket that tore will tear again.
Before the repair goes back on the boat, deal with what caused it: tape the spreader tip, move the lazy jack attachment, smooth the sharp edge, change how the sail is handled. Otherwise you are buying the same repair annually.
