The topside for the MarkSetBot is an inflatable set of stacked rings that are connected to each other with buckles or snap hooks.
It is easiest if you connect the 4 rings to each other before inflating.
When inflating the topside, it's recommended to begin inflating the top ring first. This way, you can connect the topside to the hull and install the splashguard while simultaneously inflating the rings for the speediest assembly. The bottom ring should be deflated when you connect the topside to the hull and install the splashguard, but the other three rings can be full.
Here is how to assemble the topside:
Here is how to roll-up the topside when you want to stow or ship it.
