Remember the Walker Bay Airis inflatable kayak I wrote about last winter? It’s inflatable, but it didn’t feel floppy or unstable at all. I was impressed.
 
The Walker Bay AirDock uses the same internal Air-Web construction matrix, allowing the platform to maintain its flat shape at relatively high pressure. I haven’t seen one in person, but if it’s anything like the Airis, I expect it to be firm and stable.

That definitely appears to be the impression Walker Bay wants to give:

In addition to the Air-Web fibers, AquaDock features another stability-enhancing innovation with a fancy name: Aqua-Loc, not to be confused with Tone-Lōc.

The Aqua-Loc ballast bags help hold the corners DOWN, and also keep the whole platform from sliding around on the water. Without them, the platform might just skate out from under its occupants!

I can imagine using one of these as a swimming or sunbathing platform, an extra “patio” while at anchor or at the marina, and perhaps even as a dinghy dock.
