Ours is on an entire pontoon boat, is kind of a light grey woven pattern. Yes, expensive, but like Jim S, this could be my last boat and I wanted the best. It gets hot like fire! Easily as hot as the alum. dock when you are barefoot! Still love the stuff. Just have something on your feet in hot weather.
Only downside I've experienced, I made the mistake of spilling some gas on it when filling the tank early on (a cup or 2 max). That stain will not come out. It's like it melted the backing a little, and that came up through the weave discoloring it a bit. That was a couple of years ago, and admittedly, the stain is fading a bit. Not nearly as noticeable as it was at first. No other downside. Washes up nicely easily.
