What happens when you use slab reefing on a sailboat?
Most of the time, when a sailboat uses its slab reefing it will subsequently wear out the webbing attachments to the tack rings. Therefore a failure of the webbing connection to the mainsail luff slides will be caused. As I’ve mentioned before, the most practical and easy solution to this is to be equipped with twine, a webbing, a needle, and a sailor’s palm. In case you don’t have the correct size of webbing, then Spectra cord can attach a slide fairly well.
Can you use dacron tape on sails?
You can use a Dacron patch for almost everything except spinnakers. Dacron can even stick to many laminate sails on the film side, but not on some resin-based and silicone-covered sails.

However, due to its design, when the surface you lay it on is flat it might pose you a problem. So do some temporary tucks and folds in the cloth, but away from the rip, and try to keep it flat. So, be patient and follow the below-mentioned procedure:
