Even though it didn't need it, the old canvas on our Krogen Manatee was a "toast" colored Sunbrella, and even though it went OK with the character of the boat, it didn't go well with our plans of color scheme, etc.. *I was shocked at the great condition of the old canvas, windows, zippers and fasteners. *When I commisioned new canvas to be made, I asked the same guy (Zak at Marine Seam, Daytona Beach, FL) to outfit our new canvas with the same fastener layout. *That involved common sense fasteners at real stress points, press studs at a few areas that are often opened, and the entire bridge-deck wind breaker canvas was done in velcro where it would be rarely, but easily removed. *I found the old canvas velcro to be virtually pristine, but I don't know about how often it was removed. *My guess is that velcro wouldn't be the way to go with something that gets heavy use and is pulled apart on a regular basis, but I have no problem with the press studs, and as long as the canvas has sewn reinforcement wherever there is a fastener, regardless of what type.
**Here's shots of the original boat as purchased, the old canvas laid out for inspection, and two shots of the fasteners on the new stuff. *Never had any rust to speak of on these fasteners, and we're in FL on salt water.
