Thomson Sails provides a repair facility for most types of sails. I also specialise in Sailboard and Kite repairs, being one of the best known and respected in that field around Melbourne.
(I was one of the last sailboard sail manufacturers in Australia)
Whatever kind of problem you have with your sail, I can most likely fix, even if you think your sail is beyond repair, there is a fair chance that it can be saved and serve you for a long time yet. General maintenance is also offered..check overs, replacement of battens, change of numbers, shape and luff curve alterations, new reefs, dimension alterations, you name it.
I also can do a miriad of covers for just about anything, in a wide range of materials, as well as shade sails and screens.
Feel free to give me a call if you need anything done.
