Their problem isn't the design, it's the crappy sunbrella they have used. FW replaced my canvas under warranty because it developed pinhole through it that appears to be the canvas just dissolving. This one is now 3 yrs old and it is doing the same thing. It's that sunbrella with the rubber backing. Absolutely sucks down here. Have a cool morning with the humidity down here and you are "rained" on under the canvas because of condensation dripping.
They did make my cockpit cover and it has held up well. They used "normal" sunbrella on it and I have had no issues other than it needing to be re-stitched in a few areas.
Get some recommendations for good marine canvas makers and have a local make it. I will be needing to replace my whole bimini probably next season. I have already had my local guy patch my bimini in 6 places. Fortunately I just see the stitching from below otherwise it would bug the hell out of me. Crossing fingers for one more season!
