We’re very happy with our Dock Blocks.  They’re nice and sturdy and maintenance is easy.  I’ve also noticed that the gulls must not like the surface of the blocks, so we don’t have to spend time scrubbing gull poop off like our neighbors with wooden platforms do.  I’ve attached a couple of photos.  One is pretty distant, I recognize.  The other doesn’t have great focus clarity but comes with a dog as a bonus!

Warmest regards,
