One of the most common questions we get asked is about the stitching.
The concern is understandable as the integrity of your sails and canvas depend on stitching.
In no way does the Vacuwash process have any detrimental effect on the stitching in sails and canvas.
This best way to prove this is to highlight that every sail/canvas washed is put into a bag, these bags over the past 5 years would themselves have been through the Vacuwash process thousands of times, well more than any sail over its lifetime.
The bags are still in perfect condition and can still easily hold the weight of your wet sails as they are lifted out of the Vacuwash tank. You are more than welcome to inspect the bags at the North Curl Curl factory, and there are pictures attached below.
Over half of our customers are returning ones, that says a lot of their satisfaction. My own sails have been Vacuwashed three times, they handled Bass Strait in 40 knots, easily proving that the stitching is not affected.
Canvas is slightly different as it always in the UV, it is the UV that kills the stitching in dodgers, biminis etc, these need to be re-stitched every 3-5 years (also depending on the stitching thread used). It follows that when I receive canvas to clean the stitching has been in the UV for a while, and thus will need re doing. Putting canvas back on the boat without having it restitched will usually result in it coming apart as point loading a zip will exert pressure on the stitching that is not normal, causing it to fail.
UV is the killer of stitching, not cleaning.
