That would depend on a lot of factors, but in our case, it works for us.
The Takacat dinghy weighs around 70 pounds. Getting it up there couldn't be described as easy but I have a process that makes it pretty straight-forward. I stand the dinghy on end on the swim step and let it lean forward to rest on the back of the bimini frame. From there, I can straddle the outboard and push the dinghy up over the bimini. I've been intending to install a couple of rails over the canvas to keep the dinghy from abrading the canvas but haven't seen much wear so far. The dinghy is stored upside-down and without the motor attached. Launching is just a matter of pushing it off.
Our rear stanchions that support the bimini frame are not the standard configuration; ours are detachable and we can remove them, so they're likely less stable than the standard permanent factory stanchions. We had this modification made at the factory to give us more room for fishing. The bimini frame (without the dinghy) will easily support itself without the rear stanchions. When the dinghy is on top and I remove the rear stanchions, I install a support on the ski pole that holds up the back of the bimini frame.
