To notice out, we spent a mean solar day with John Gregal, possessor of Mount Vernon Sheet Works in Arlington, Virginia, a canvass fabrication and repair company serving boaters on the Potomac River.

After most three years, the bungees stretch or break from weather exposure. To remove the broken bungee, pry off the backing slice with a screwdriver. Await to interruption it.
To supercede, sandwich the canvas betwixt the two halves and printing the barbed male side into the female person side. Merely make certain y'all position it correctly because you lot can't get information technology apart (without destroying information technology) once information technology snaps airtight.

When it comes to zippers, handymen tin make one repair but everything else needs to be done at the yard. If the slider tab that you pull up to close the zipper breaks, cut off the terminal tooth on the zipper, slide off the one-time tab and slip on a new one. Then cook the last molar of the zipper or crimp a zipper stop over it to keep the new tab from sliding off. Zipper parts are bachelor from full general sewing supply houses besides every bit specialty marine retailers.
Unfortunately, that's the only attachment repair yous can do yourself. "Once a attachment separates backside the slider, information technology's done," Gregal said. The plastic teeth on the attachment are shaped like a mushroom, and that expanded shape holds the seam closed. As the plastic teeth degrade, they lose their grip and the zipper needs to be replaced.
You can't replace the zipper yourself unless you have an industrial-strength sewing car to penetrate a fabric such as Sunbrella and the zipper with the appropriate UV-resistant thread.

Practise Information technology Yourself: Repairing a Seam
When it comes to split seams, Gregal said, "I see a lot of bootleg repairs that are done with sparse thread." You can repair split seams on your canvas, but your sewing machine has to be up to the chore. "The cardinal to canvas is a UV-resistant thread," Gregal said.

The offset time the repair is made, you lot demand to pin downwards the new vinyl to maintain the shape of the window. This requires an industrial-strength sewing machine to dial through the canvass and the two layers of vinyl. With the new vinyl in place, cut out the old cloudy stuff and you'll see clearly once more. Gregal estimated that replacing the clear vinyl would cost about 70 percent less than getting all new sail.
Rent Someone: Replacing Mutual Sense and Lift-the-Dot Fasteners
Common Sense and Elevator-the-Dot fasteners are high-tech snaps used where a conventional stud and female person combination won't concur. The Mutual Sense and Lift-the-Dot fasteners toll less than a cadet each and have locking mechanisms that secure the cover in place. The Common Sense fastener has a twisting rectangular stud on the bottom and a grommetlike female fastener in the cover. Slip the female side over the male stud and spin the latter to lock information technology down.
A Elevator-the-Dot fastener is similar with male person and female person halves, but they snap together instead of having any twisting parts. Gregal said that both are installed similarly to a snap and that a layman could handle them, but the press/pliers cost most $300, which would make information technology cost-prohibitive. Take it to the pros.
Do It Yourself: Pulled Snap
More frequently than not, the female part of the snap on the cover breaks, not the male person office that'due south screwed into the gunkhole. (Be a captain and instruct your coiffure not to yank the embrace to try to release all the snaps at one time!) You tin can get replacement snaps at chandleries similar Overton'southward and W Marine. Female snaps come up in either brass or stainless steel. Stainless steel is meliorate, only don't mix metals, particularly if you boat in salt h2o. Gregal recommends doing the work yourself if you demand fewer than x snaps replaced. To become an idea of pricing, Overton'southward sells its 73-piece snap kit (chrome-plated contumely) with snaps plus crimping pliers for $24.99. Yous clasp together the two halves of the female cap onto the fabric. Higher-quality crimpers volition mushroom the cap properly. Cheaper tools volition separate information technology, which can lead to premature failure. That's why Gregal noted that the Hoover Pres-Due north-Snap is the professional person's preferred snap installation tool ($201.95 on amazon.com). For boaters who have difficulty removing snaps, the Top-Snapper ($20, overtons.com) is a spatulalike tool that you slide under the snap to pry it up without tearing the snap free.
For the male side of a snap (the stud), which is on the boat, you just demand a screwdriver, but some less expensive boats have their snaps riveted in identify. To supervene upon these, you need to drill out the rivet and replace it with a screw-in stud. To keep the gelcoat from cracking when drilling, Gregal uses a ane-8th-inch countersink scrap to flare the pigsty. A countersink is used to broaden a hole so that a screw volition sit flush or below the surface of the material into which it is driven. With the hole drilled, it's simply a matter of bedding the screw with marine sealant and driving it into the fiberglass. Coat snaps with lip balm to make them easier to use.

A grommet is a reinforced metal band about the size of a quarter in a embrace or T-height. Information technology's used to pass cords through. Much like on a snap, yous use a die to printing a grommet into fabric. Gregal said that, if you're only replacing a couple, you can press it into the cover by placing the die in the cover and positioning it on a block of wood. Then you pound it with a hammer to close the grommet around the fabric. If you're replacing a serial of grommets in a T-acme or similar application, Gregal suggested having a professional do the work. The best grommets are corrosion-resistant stainless steel.

Rent Someone: Repairing a Dissever Between Canvas and Articulate Vinyl
Where vinyl is concerned, fifty-fifty a short split-seam repair is more difficult to do than a repair in an all-fabric seam. "Information technology'south harder to sew the vinyl because it's thicker, so this one should be left to the k," Gregal said. "When the clear vinyl comes into play, it takes a stronger motorcar to punch through the thicker vinyl of the windows."

You lot can also use a crayon to "describe" a waxy protective movie onto the snap or zipper. Make this part of your spring commissioning and autumn layup regimens.

Do It Yourself: Patching a Hole
Gregal considers Sunbrella the best cloth for boat covers because of the fabric'due south composition; professionals cut information technology with a hot knife. Almost laymen don't own such a knife, but if at that place'south a pocket-sized hole that you desire to patch, seal it off with a carefully wielded cigarette lighter or soldering atomic number 26, and so sew together a patch over information technology. Utilize a sewing machine whenever possible. "It would look pretty well butchered if you tried to stitch it by mitt," Gregal said.

New Sail Buying Tips
If your canvas needs to exist replaced, Gregal has some tips for what you should look for. First, make sure the new cover is made from Sunbrella, or if you boat down Due south and want a lite-color material, he recommends Stamoid, which is plastic-based. Light-colour Sunbrella gets dingy easily, though. Make sure the company making your cover uses UV-resistant oversize thread. It comes in two primary sizes, 92 and 138. The higher number is the thicker thread, and if yous're planning to keep your boat, request Tenara thread, which Gregal calls "Gore-Tex on a spool." Information technology's impervious to rot. For zippers, select No. x large-molar, and make certain they're double-stitched. Ask that the binding exist positioned on the outside to protect the plastic zipper from the dominicus. Snaps should exist stainless steel, and to ballast the poles that support the cover, enquire for a Vent-So-Port, a plastic cap almost v inches in bore that ameliorate distributes the weight of the canvas.
