Thanks! I've definitely been going back and forth about steel cable vs chain. Because of the fact that I currently have no idea how high I'll need to hang the Kessils, the chain makes it really easy to raise/lower the canopy, but I'm thinking once the system is up and running I may replace the chain with steel cable.I think the canopy looks great, to soften the look you could replace the heavy chain with some thin steel cable, which for this application should be plenty strong. Think the wire shelving will hold up to saltwater exposure? Should be fine if you canopy is high up enough.
I'm fairly sure that the canopy will be high enough that I won't have to worry about saltwater corrosion on the shelving, but if it ends up being lower than I'm thinking I'll definitely keep an eye on that.
